ABSTRACT:
A method, and related apparatus, for coherently demodulating phase-modulated data which is coherently transmitted (i.e., without the use of differential encoding of the data) on Rician fading channels. The method uses phase unwrapping and phase interpolation, in conjunction with block phase estimation, to achieve a performance comparable with coherent detection of coherently transmitted data while reducing processing requirements.
