摘要：
In this paper, we proposed a technique that jointly corrects the frequency offset and suppresses the multiple access interference (MAI). Since the value of frequency offset of each user signal is usually not the same in the uplink, therefore; we need to separate the desired user signal from the mixed signal in order to be able to estimate the frequency offset. We use the parallel interference cancellation technique for the signal separation. Performance of our purposed scheme in term of BER comparable to conventional PIC and matched filter.
