摘要： A method and apparatus for communications channel symbol recovery that improves equalizer performance adds together the log-likelihood ratios (LLRs) of different decision delays rather than using LLRs corresponding only to a single decision delay. A low complexity method comprises, determining an initial coarse delay and a set of fine delays (1003), estimating a training sequence and filter taps set for each fine delay (1007), determining an error function for each fine delay (1009), and linearly combining the filter taps (1013) for determining the symbol estimates (1017).

摘要： A method for reducing interference in a desired signal in a GSM communication system uses a finite-impulse-response filter for alternate linear equalization. The method includes a first step (300) of inputting a burst of data of a received waveform including interference from a channel of the communication system. A next step (302) includes training the finite-impulse-response filter with a set of symbols of specific quadrature phase, known a priori, in the burst of data of the received waveform. For example known real only and imaginary only symbols are alternatively selected from a midamble of the data burst. A next step (304) includes operating on the received waveform with the finite-impulse-response filter to alternately linearly equalize the burst of data to provide an estimate of the desired signal.

摘要： A base station (103) assigns a set of mobile stations (101) to a group wherein the group will share a set of radio resources (770). A control field (1103) may be sent with a payload field (1105) wherein the control field (1103) and payload field (1105) are sent using a single Orthogonal Variable Spreading Factor or a single Walsh Code (1101) wherein various modulation and coding schemes may be applied to the control field (1103) and payload field (1105) such that different modulation and coding schemes may be used within the single channel. HARQ is handled by sending a single retransmission if a NACK message is received or no ACK/NACK message is received at all.

摘要： Embodiments include methods and apparatus associated with wireless multicast and/or broadcast services. A base station (102) transmits data codes (504, 604, 702) within a radio frame (300). The data codes are Code Division Multiple Access (CDMA) data codes, in an embodiment. The base station also transmits a Time Division Multiplexed (TDM) synchronization code (502, 608, 706), in an embodiment. The base station discontinuously transmits (1004) a portion of a radio frame slot that is coincident in time with a duration of the TDM synchronization code, in various embodiments. The discontinuously transmitted portion of the radio frame slot may include Transport Format Combination Indicator (TFCI) bits (510), pilot bits (710), or data bits (612), in various embodiments. A base station's transmissions may be synchronous in time and frequency with the transmissions of other base stations.
