摘要： A cellular communication system comprises a Multiple-In Multiple-Out, MIMO, transmitter (101) and receiver (103). The MIMO transmitter (101) comprises a message generator (303) for generating MIMO messages comprising selected training sequences and transceivers (305, 307, 309) transmitting the messages on a plurality of antennas (311, 313, 315). The training sequences are selected by a midamble selector (317) from a set of training sequences in response to an associated antenna on which the message is to be transmitted. The set of training sequences is associated with the cell of the MIMO transmitter and comprises disjoint subsets of training sequences for each of the plurality of antennas. The receiver (103) comprises a transmit antenna detector (419) which determines which antenna of the MIMO transmitter the message is transmitted from in response to the training sequence of the received message.

摘要： An Orthogonal Frequency Division Multiplex (OFDM) communication system comprises OFDM transmitters (103-109) and an OFDM receiver (101). The system comprises a subcarrier status data controller (200) for transmitting subcarrier status data to the OFDM receiver (101). The subcarrier status data indicates the active subcarriers of the OFDM transmitters (103-109). The OFDM receiver (101) comprises a receiver (201) which receives a signal comprising a desired signal component from a first OFDM transmitter (103) and interference from at least one interfering OFDM transmitter (105). The OFDM receiver (101) further comprises a subcarrier status processor (203) which receives the subcarrier status data and a channel estimator (205) which determines channel estimates for at least an air interface communication channel from the first OFDM transmitter (103) and an air interface communication channel from the interfering OFDM transmitter (105). An interference mitigation processor (207) performs interference mitigation of the interference in response to the subcarrier status data and the channel estimates thereby providing improved recovery of the data from the first OFDM transmitter (103).

摘要： A coherent or a noncoherent transmission mode is automatically selected for a transmission on the basis of an estimated Doppler frequency shift due to a motion of a mobile terminal. A coherent mode is selected if a pilot signal overhead is not excessive to uniquely characterize a Doppler frequency shift, as at lower carrier frequency times relative velocity products. A noncoherent mode is selected if a pilot signal overhead would be excessive to uniquely characterize a Doppler frequency shift at higher carrier frequency times relative velocity products. Both the coherent and noncoherent modes have respective advantages for their respective carrier frequency time relative velocity regimes.

摘要： Embodiments of the invention provide for allocating spectrum in a wireless communication system that supports simultaneously at least a first mode of operation and a second mode of operation. Logic is arranged for determining a proportion of spectrum required for the wireless communication unit to operate simultaneously in both the first mode of operation and the second mode of operation. Logic for allocating spectrum allocates a temporary guard band between a first portion of spectrum for the first mode of operation and a second portion of spectrum for the second mode of operation for use whilst the wireless communication unit operates simultaneously in the first mode of operation and second mode of operation.

摘要： A method and arrangement (100) for PRACH burst channel detection in a UTRA TDD wireless communication system in which training sequences are constructed from a single periodic base code. Unwanted cross-correlation peaks, having magnitude less than correlation peaks, are removed (440) from the correlator outputs, maintaining optimal signal-to-noise ratio of the channel estimates, providing a low probability of false detection, and extending the cell size of a CDMA network to that determined by the guard period duration. The cell size can be extended further by ensuring that no transmissions are scheduled for the timeslot subsequent to that in which the channel estimation bursts are scheduled.

摘要： An efficient scheme for CDMA coding constructs codes by generating longer code sequences (430) via concatenation, from an existing set of short sequences (410, 420). The sequences may be spreading, scrambling and or training or channel estimation (such as midamble) sequences. The invention allows extension of sequences without performing an exhaustive search for sequences with optimal desired properties, as well as extension of the sequence duration to improve the detection of wanted signals via the use of a conventional matched filter, a multi-user detector or an adaptive filter/equaliser.

摘要： A tire rain protector made of a mushroom shaped polymer body having a reverse taper male thread formed thereon having a threadform with three varying geometric parameters. The thread thickness, thread height, and thread crest width all increase from the top of the tire rain protector body to the bottom of the body. These three features along with a thread that begins at the underside of the cap enable for a device that is easy to install and forms a secure tight seal on a tire. When installed, this dome-like device diverts rain from collecting into the concave liner (inner sidewalls) of a horizontally stacked tire.

摘要： Disclosed is a portable apparatus for batting practice which aids in the development and/or improvement of a batter's ability to strike a baseball/softball with a baseball/softball bat. The apparatus consists of ball-targets, affixed to a hub, that rotate about a horizontal axle. Suitably, the hub is defined by a strap and clamp assembly.The apparatus may be affixed to any vertical assembly, but will typically be affixed to a standard vertical assembly, commonly known as a batting tee. Once so affixed, the apparatus may be adjusted up or down along with the tee, to allow for batters of varying heights to use the apparatus. The batter strikes the target, with the selected implement, in this case a baseball/softball bat, causing the target to rotate around the horizontal axle, eventually returning a target once again to the upright and proper position, allowing for further training using said apparatus.

摘要： A tape course generator produces tape course definitions for use in programming a CNC composite tape lamination machine. The tape course generator includes a reference surface parameterizer that maps a contoured surface onto a parametric reference surface, and a reference plane instantiator that maps the reference surface onto a reference plane. The tape course generator also includes a tape boundary plotter that plots a tape boundary, and a boundary mapper that maps the tape boundary and a ply boundary into the reference plane. In addition, the tape course generator includes an intersection locator that identifies intersections of the ply boundary and the tape boundary, and a tape course delimiter that defines tape cuts and determines which points in the reference plane are within a tape course. Moreover, the tape course generator includes a tape course transformer that maps the defined tape course back onto the contoured surface.
