发明名称 METHOD FOR OVERUSING FREQUENCIES TO PERMIT SIMULTANEOUS TRANSMISSION FROM TWO OR MORE USERS
摘要 <p>A system is provided for increasing the number of users capable of communicating over a wireless network to permit multiple users (22, 24) to transmit information simultaneously on the same channel (S1, S2, f1) or frequency in which a viterbi decoder-based signal separation system is used to pull apart or uncorrupt the otherwise interfering signals on the channel. In one embodiment, two users (22, 24) are assigned to the same channel (f1), with a joint parameter estimation offsets and phase of incoming signals. The joint parameters estimated by the parameter estimation unit (50) are applied to a signal separator (600) which covers and pull apart the two signals. The subject system is capable of accumulating more than two simultaneously transmitted signals to provide signal packing over existing channels without require new waveforms through the utilization of stripping techniques and tail chopping techniques so as to minimize the computational load involved in separating the signals.</p>
