标题： Performance comparison of multi-user detectors for the downlink of a broadband MC-CDMA system

摘要： 本文研究了宽带多载波码分多址（MCCDMA）系统下行链路的多用户检测技术，如并行和串行干扰取消（PIC & SIC）、通用最小均方误差（GMMSE）和多项式MMSE。评估了误比特率（BER）和误帧率（FER）结果，并与单用户检测（MMSEC、EGC）方法进行了比较。性能评估考虑了系统负载、信道编码和调制方案。 显示英文摘要

摘要： In this paper multi-user detection techniques, such as Parallel and Serial Interference Cancellations (PIC & SIC), General Minimum Mean Square Error (GMMSE) and polynomial MMSE, for the downlink of a broadband Multi-Carrier Code Division Multiple Access (MCCDMA) system are investigated. The Bit Error Rate (BER) and Frame Error Rate (FER) results are evaluated, and compared with single-user detection (MMSEC, EGC) approaches, as well. The performance evaluation takes into account the system load, channel coding and modulation schemes.
