Abstract
A receiver apparatus for receiving an OFDM radio signal comprising a first plurality of subcarrier-symbols, modulated on a corresponding plurality of subcarriers, and a second plurality of subcarrier-symbols, modulated on the corresponding plurality of subcarriers, to generate first and second bit sequences, the first bit sequence being an interleaved version of the second bit sequence according to a predetermined interleave function. Soft-output decoder logic generates a first soft-bit sequence for the first plurality of subcarrier-symbols, and a second soft-bit sequence for the second plurality of subcarrier-symbols. Combiner logic combines the soft-bit sequences, with the soft-bit sequences either both in an interleaved state or both in a non-interleaved state, by combining a respective soft-bit having a bit position in the first soft-bit sequence with a respective soft-bit having a same bit position in the second soft-bit sequence. Hard-output decoder logic outputs a hard-bit sequence representing the transmitted bit sequence.
