Abstract : This invention relates generally to the field of coherent signal detection, and more particularly to a digital coherent detector for directly sampling and digitizing an IF signal. Objects of the present invention are: to significantly increase the phase accuracy obtained in the coherent detection of a signal; to eliminate the requirement for IF-to-baseband conversion in a coherent detector; to directly detect IF signals in a coherent detector; and It is yet a further object of the present invention to significantly reduce the hardware and cost in implementing a digital coherent detector for IF.
