Abstract
A method for using coherent modulation and coding to improve the error-rate of non-coherent frequency-hopping data transmission systems includes aiding phase estimation by sending, in each hop, one or more reference bits, which are known to the receiver, and using the reference bits along with the data bits received in that same hop to estimate the channel phase. The data bits are then demodulated using the estimaated phase. The method also uses weighting of the demodulator output during each hop by a factor expressing the confidence level for the correctness of the phase estimated for that hop. Apparatus for implementing my novel methodology is also provided.
