摘要： A method for space-time-frequency coding pieces of data includes receiving a stream of a plurality of pieces of data in a multi-antenna transmission system, where the data may comprise a stream of orthogonal frequency division multiple access (OFDMA) symbols, orthogonal frequency division multiplexed (OFDM) symbols or the like. The pieces of data are then coded across space, time and frequency dimensions based upon a plurality of space-time-frequency (STF) codes. The pieces of data are coded such that one or more STF codes in the frequency dimension differ from one or more other STF codes in the frequency dimension. In this regard, the frequency dimension can include a plurality of frequency bins such that the pieces of data can be coded in a manner whereby the plurality of STF codes sequentially circulates through sets of at least one frequency bin in the frequency domain.

摘要： A transmitter and an applicable method comprising an antenna system for achieving two transmit paths, a first modulator for modulating a signal to be transmitted into complex modulation symbols, and a second modulator for constructing layered channel symbols as linear combinations of the complex modulation symbols is disclosed. The second modulator constructs channel symbols by using first and second non-zero coefficients when performing the linear combination. The ratio of the first and second coefficients is not a real number. The channel symbols are transmitted by using a first non-zero total power for transmission on a first transmit path, and a second non-zero total power for transmission on a second transmit path, wherein the first and second total powers are not equal.

摘要： The invention relates to a cellular radio system and a method of locating a terminal in a cellular radio system having in each cell at least one base station 104 communicating with the terminals 100 within its area. The base station measures channel parameters from the signals transmitted by the terminals. The coverage area of each base station is modelled by a digital map. To enable accurate localization of the terminals, to each point on the digital map is added a model of the channel parameters of a signal to be transmitted from the point. The channel parameters estimated from the signal of the terminal are compared with the parameters at different points on the map, and the terminal is located on the basis of the comparison.

摘要： A signal detection method in a TDMA mobile system with co-channel interference and receivers implementing the method. In the method, a primary signal (r.sub.1) and at least one interfering co-channel signal (r.sub.2 -r.sub.N) are received on the same TDMA channel (F.sub.1, TS.sub.3). The co-channel signals propagate through multipath channels (h.sub.L,1 . . . h.sub.L,N) independent of one another, which provide them with a unique wave form coding. In addition, the co-channel signals have different but known training sequences. The multipath channel estimates of the primary signal (r.sub.1) and the at least one interfering co-channel signal (r.sub.2 -r.sub.N) are determined through the received training sequences. After this, the primary signal is detected by utilizing the transmission channel estimates of both the primary signal and the at least one interfering co-channel signal.

摘要： In the overlayed operation of two cellular radio systems one of the two systems is a small-scale or indoor system and the other is a large-scale or outdoor system. The indoor system monitors the operation of the outdoor system and detects, which part of the available radio resources are temporarily not in use in the outdoor system. The indoor system dynamically selects an unused outdoor channel for indoor operation. The indoor radio traffic is divided into cyclically occurring time slots and some of the slots are used for monitoring the existing radio communication on other outdoor channels so that fast changes according to changing traffic and interference conditions are possible.
