Soft repetition code combiner using channel state information

摘要

An embodiment is a method and apparatus to decode a signal using channel information. A channel state estimator generates a tone value representing channel information. A quantizer quantizes the tone value. A combiner combines de-interleaved symbols weighed by the quantized tone value. A comparator compares the combined de-interleaved symbols with a threshold to generate a decoding decision. Another embodiment is a method and apparatus to decode a signal using averaging. A channel estimator provides a channel estimate. A multiplier multiplies a quantized output of a demodulator with the channel estimate to produce N symbols of a signal corresponding to a carrier. A de-interleaver de-interleaves the N symbols. An averager averages the N de-interleaved symbols to generate a channel response at a carrier.
