Abstract
A receiver apparatus is configured to receive a radio-frequency signal comprising a first subcarrier comprising first subcarrier symbols and a second subcarrier comprising second subcarrier symbols, wherein the first subcarrier symbols and the second subcarrier symbols both encode a same bit sequence in a respective first subcarrier symbol and a second subcarrier symbol. Soft-output decoder logic calculates respective log-likelihood ratios for each of the first subcarrier symbols and generates a first output sequence comprising the respective log-likelihood ratios calculated for the first subcarrier symbols and similarly generates a second output sequence. Combiner logic combines the output sequences by adding or subtracting a respective log-likelihood ratio with a respective log-likelihood ratio calculated for the respective second subcarrier symbol to obtain a combined log-likelihood ratio for a respective bit of the bit sequence, and outputs a combined output sequence comprising a respective combined log-likelihood ratio for each bit of the bit sequence.
