ABSTRACT:
A digital receiver apparatus and method, designed for multiple simultaneous users, digitizes a received analog RF signal and performs multiple frequency translations of the signal so that desired stations are grouped into a common frequency band separate from the remaining stations. This frequency band is then isolated, and the individual selected stations are digitally separated, demodulated and processed to provide multiple simultaneous outputs. The frequency translations are preferably performed initially on a time multiplexed basis. Isolated station separation is performed either by time multiplexing, or by the use of multiple phase or tan locked loops.
