Abstract:
1. A receiver for processing a received signal encoded with a codeword and mapped to two layers comprising: a first and a second equalizer for equalizing the received signal; a plurality of demodulators for demodulating a respective equalized signal; a decoder for decoding the demodulated signal by extracting soft bits from the demodulated signal, wherein each soft bit comprises a probabilistic estimate of a value of a corresponding bit of the received signal; a modulator for modulating the decoded signal by generating soft symbols based on the extracted soft bits, wherein each soft symbol represents a probabilistic estimate of a value of a corresponding symbol in the received signal; a demapper for demapping the modulated signal to soft symbols corresponding to each of the two layers; and a first and a second inter-layer interference canceller for cancelling interference utilizing the demapped soft symbols, wherein
