摘要： A relay, for use in an indoor multi-carrier radio frequency wireless communications system, stores multiple predetermined phase adjustment profiles. The best of the stored phase adjustment profiles is selected by a receiver, which sends a message to the relay, indicating the profile to be used. The selected stored phase adjustment profiles is then applied to a multi-carrier signal received at the relay, to form a phase adjusted multi-carrier signal, and this phase adjusted signal is then transmitted from the relay.

摘要： In a transmission system with a transmitter coupled to a receiver a main signal encoded according to a coding property is transmitted together with an auxiliary signal (AUX) In order to transmit the auxiliary signal without needing additional space in the transmission frame, the auxiliary signal is transmitted by changing the coding property according to a predetermined sequence. This is done by means of the sequencer. In the receivers, the decoding of the predetermined sequence is performed by a decoder.

摘要： Transmitters (116) for transmitting information and receivers (126) for receiving the information are defined by the information comprising a primary message and a secondary message combined in a same transmission or a same reception, which primary and secondary messages comprise communication protocol signaling messages, to avoid that a protocol conversion arrangement needs to be added to and to be placed between the transmitter (116) and the receiver (126). This increases the efficiency of the transmitter (116) and the receiver (126). The primary and secondary communication protocol messages are in accordance with first and second standards such as 802.11 a and later standards such as 802.11 n. The receiver (126) is able to detect the primary or secondary communication protocol message in case of the receiver (126) being in accordance with the first or second standard. The secondary message is embedded in the primary message via a modulation or via a selection of a subset of a set of a modulation constellation.

摘要： Receivers (1) for receiving encoded block signals and comprising processor systems (2) decode block signals by using Viterbi algorithms for finding a first candidate/path in a trellis (18) and by generating cost signals for finding further candidates/paths in said trellis (18). To reduce storage capacity, cost signals are combined for series of branches and cumulated cost is compared with thresholds. While searching for said further paths, a search for a further path is made in view of cumulated cost exceeding a threshold or not. The insight of indirectly constructing a list of candidates and the basic idea of more directly constructing said list brings more control. These receivers are less complex, and are further improved by introducing increasing thresholds per trellis and successive combining and different trellis directions for generating and cumulating cost signals and combining in a lexicographical order, and using a check sum for list reduction and by making error detections.

摘要： A record carrier (1) is described which has a servo track (4) indicating an information track (9) intended for recording information blocks, which servo track (4) has a variation of a physical parameter, a so called wobble. The wobble is modulated for encoding record carrier information, such as addresses. The servo track is subdivided in modulated parts in which the frequency and/or phase of the variation deviates from the wobble frequency, and non-modulated parts. The slope of the wobble is substantially continuous at transitions between the modulated and non-modulated parts by using wobbles (25,26,27,28) starting at the maxima or minima of the wobble in the first part of the modulated parts.

摘要： A method of signal processing for a receiver for OFDM encoded digital signals, for counteracting inter-carrier interference (ICI) caused by Doppler broadening. The OFDM encoded digital signals are transmitted as sub-carriers in several channels, which form OFDM blocks. The method comprises estimation of a channel transfer function (Ĥ1) by a channel estimation scheme in each sub-carrier and estimation of data (â1) by a data estimation scheme from said channel transfer function (Ĥ1) and a received signal (y0). Then, a derivative (Hj′) of said channel transfer function in each sub-carrier is estimated by a temporal filtering; and the inter-carrier interference (ICI) is removed from said received signal by using the estimated data (â1) and the estimated derivative (Hj′) of the channel transfer function in order to obtain a cleaned received signal (y1).

摘要： A method of signal processing for a receiver for OFDM encoded digital signals. The OFDM encoded digital signals are transmitted as data symbol sub-carriers in several frequency channels. A subset of the sub-carriers is in the form of pilot sub-carriers having a pilot value (ap) known to the receiver. First, a received signal (y0) is obtained, followed by a first estimation of a pilot channel transfer function (H0)at pilot sub-carriers from said received signal (y0) and said known pilot values (ap). Then a second estimation of a channel transfer function (H1) is performed at all sub-carriers from said pilot channel transfer function (H0). A third estimation of a derivative (H′1) of the channel transfer function (H1) is performed from the channel transfer function (H1) and a channel transfer function (H3) from a past OFDM symbol. Finally, a fourth estimation of a cleaned received signal (y1) is performed from said derivative (H′1), said received signal (y0) and said pilot values (ap) by removal of pilot-induced interference.

摘要： A method of signal processing and a signal processor for a receiver for OFDM encoded digital signals. The OFDM encoded digital signals are transmitted as data symbol sub-carriers in several frequency channels. A subset of said sub carriers is in the form of pilot sub-carriers having a value known to the receiver. A first estimation of channel coefficients (H0) at said pilot sub-carriers is performed followed by cleaning of the estimated channel coefficients (H0) at the pilot sub-carriers. Then, a second estimation of channels coefficients (H1) is performed at the data symbol sub-carriers. The first estimation is performed by dividing received symbols (yp) at said pilot sub-carriers by the known pilot symbols (ap). the channel frequency response is supposed to vary linearly within one OFDM symbol. Therefore for each symbol and sub-band, a channel frequency response and its derivate are calculated or interpolated.

摘要： The invention relates to a method of decoding possibly multilated code words (r) of a code (C), wherein an information word (m) and an address word (a) are encoded into a code word (c) of said code (C) using a generator matrix (G) and wherein said address words (a) are selected such that address words (a) having a known relationship are assigned to consecutive code words (c). To provide a reliable way of decoding making use of the known relationship, a method comprising the following steps is proposed: decoding the differences (D) of a number (L−1) of pairs of possibly mutilated code words (rib, ri+1) to obtain estimates (u, v) for the differences of the corresponding pairs of code words (ci, ci+1), combining said estimates (u, v) to obtain a number (L) of at least two corrupted versions (wj) of a particular code word (c), forming a code vector (z) from said number (L) of corrupted versions (wj) of said particular code word (c) in each coordinate, decoding said code vector (z) to a decoded code word (c′) in said code (C), and—using said generator matrix (G) to obtain the information word (m) and the address word (a) embedded in said decoded code word (c′).
