Abstract: A wireless receiver for a distributed antenna diversity receiver apparatus comprising a pre-combining component arranged to receive an RF signal from an antenna and to recover and output an information signal contained within the received RF signal, and a combined-signal component arranged to receive the recovered information signal output by the pre-combining component of the wireless receiver and a further recovered information signal from a further wireless receiver and to perform diversity combining of the recovered information signals to obtain and output an enhanced information signal. The wireless receiver further comprises a monitoring component arranged to receive intra-packet channel reliability parameters for the wireless receiver and for the further wireless receiver, determine whether to assign a new master receiver for the distributed antenna diversity receiver apparatus based on the received intra-packet reliability parameters.

Abstract: Receivers and methods of operation are described. A receiver for a modulated signal of a communication system, comprises a demodulator to demodulate the received modulated symbols of a received signal into received soft-bits. A hard-decision decoder is arranged and configured to decode the received soft-bits into decoded bits. A feedback loop is arranged to provide feedback from the hard decision decoder to the demodulator. the feedback loop is configured to re-encode the decoded bits from the hard-decision decoder into re-encoded bits. The demodulator is further arranged and configured to iteratively demodulate the received modulated signal using an output of the feedback loop.
