Patent ID: 8107439

Claim:
A method of data receiving in a wireless communication system, comprising: demodulating and decoding a first signal received to obtain a first data packet of a user having highest received power; removing the first data packet from the first signal to generate a second signal if the first signal includes signals of more than two users; and demodulating and decoding the second signal to obtain a second data packet of a user having highest received power from the second signal, and taking the second signal as a new first signal which is processed similar to the first signal; wherein removing the first data packet comprises: modulating the first data packet to regenerate a sent signal of the user having the highest received power, convoluting the regenerated sent signal and a channel impulse response corresponding to the user, and restoring a received signal of the user received by a base station in a channel condition in which the sent signal is sent, and subtracting the restored received signal from the first signal.
