摘要： Pilot signals transmitted by different antennas in a wireless communication system using multiple transmit antennas are distinguished using different codes. In one embodiment, each of two antennas simultaneously transmit a time slot's worth of data while time division multiplexing a pilot signal with the data. The pilot signal from the first antenna is encoded with a first code such as a Walsh code and the pilot signal from the second antenna is encoded with a different code such as a different Walsh code. The different codes enable a receiver to distinguish the pilot signals when they are received to enable coherent detection of signals transmitted by both of the antennas.

摘要： Coherent channels estimates are generated for received uplink mobile-to-base signals in a wireless CDMA system, or for other types of orthogonally-modulated signals in other multiaccess systems. The coherent channel estimates are used to implement signal detection functions such as maximal ratio combining (MRC), coherent detection and interference cancellation. In one embodiment, a matched filter bank provides a set of matched filter outputs for different combinations of data symbols, multipath components of a received signal, and base station receive antennas. The matched filter outputs are processed in a coherent channel estimator to generate a set of coherent channel estimates. The channel estimates may be generated directly from the matched filter outputs, or may be generated by processing the matched filter outputs using a decorrelating detector approach. The invention also provides improved interference cancellation techniques which can be implemented using any type of coherent channel estimates.

摘要： A Multi-Code (MC) Code Division Multiple Access (CDMA) receiver receives N (where N>1) encoded signal channels over multiple air signal paths. The MC-CDMA receiver receives and demodulates the N encoded signal channels into N signal samples and includes a common circuit for time-sharing an accumulator, for accumulating the N signal samples, among a plurality of second correlators. Each of the plurality of second correlator means utilizes the time-shared accumulator to accumulate samples from each of the N signals which are then decoded into an associated one of the N signal channels.
