Abstract
In multiuser systems, the multi-user interference (MUI) degraded the system performance, especially in near-far effect environments. In this paper, an adaptive weight partial parallel interference cancellation (AWPPIC) scheme is proposed to reduce the MUIs and to improve the bit error rate (BER) performance for uplink orthogonal frequency division multiple access (OFDMA) communication systems. Simulation results show that under the near far problems for block-interleaved subcarrier assignment (BICA) scheme, the AWPPIC scheme can improve the BER performance for all users.
