摘要

本文研究了正交频分多址(OFDMA)移动通信系统中并行干扰消除(PIC)多用户检测器的性能。在多用户系统中，多用户干扰(MUI)会降低系统的性能，尤其是在远近影响环境下。为了降低上行OFDMA系统的mui，提高误码率(BER)，提出了PIC方案。仿真结果表明，在分块子载波分配方案(BCAS)和分块交错子载波分配方案(ICAS)的远近问题下，PIC方案都能提高所有用户的误码率性能。

Performance of Adaptive Parallel Interference Cancellation for OFDM Mobile Communication Systems

In this paper, the performance of parallel interference cancellation (PIC) multiuser detector in orthogonal frequency division multiple access (OFDMA) mobile communication systems is investigated. In multiuser systems, the multi-user interference (MUI) degraded the system performance, especially in near-far effect environments. The PIC scheme is proposed to reduce the MUIs and to improve the bit error rate (BER) performance for uplink OFDMA systems. Simulation results show that under the near far problems for both block sub carrier assignment scheme (BCAS) and block-interleaved sub carrier assignment scheme (ICAS), the PIC scheme can improve the BER performance for all users.
