摘要： A communications system employs a HARQ method and, for at least some transmission formats, incremental redundancy (IR) signals. For such formats, the multiple IR signals are derived from a single turbo encoded signal by forming multiple permutations of the encoded signal. The permutations are then converted to the coding rate of the selected transmission format. It is demonstrated by simulation that the present proposal achieves a better performance than the known HARQ techniques, while its implementation is simpler. For certain transmission formats, the transmitted signal in response to a retransmission request is identical to the first transmitted signal.

摘要： Multipath interference in a received wireless signal is cancelled by generating an estimated duplicate of the interference and subtracting it from the received signal. The interference duplication is performed in a truncated manner, based on a determination of which multipath signals are present, so as to reduce the complexity and processing requirement of the interference duplication. In particular, the present invention proposed that the truncation is based on a determination of which multipath signals are present, and the properties of those signals. In a first case, the truncation is that only interference between selected pairs of paths are cancelled in MPIC. In a second case, for given pairs of paths cancellation is only performed for a subset of the chips in which the corresponding two paths can cause interference.
