ABSTRACT:
Generally stated, a receiver in a communication system implements coherent channel estimation by first receiving an encoded signal and then generating a complex channel estimate from the encoded signal. The receiver then combines the complex channel estimate with the encoded signal to produce a coherent demodulated signal. After combining, the receiver decodes a version of the coherent demodulated signal to produce an estimate of the encoded signal prior to encoding.
