摘要： 为了研究无线蜂窝系统中下行链路的性能,提出了一种基于最小均方误差和空间分集的多载波系统中下行链路的联合接收方法。由干扰的类高斯特性,给出了多址干扰、蜂窝间互扰、信干燥比和误码率的详细数学表达,最后进行了仿真验证。结果表明:本文方法与仿真结果一致,从而为研究多载波系统下行链路的性能提供了一种新思路。

Abstract: To study the downlink performance of a cellular system, this paper establishes a method of combing Minimum Mean Square Error (MMSE) and location diversity in downlink of multi carrier system. The possible Gaussian interference factors in receiving the composite signals are the keys to express the theoretical conditional Bit Error Rate (BER) in a given set of channel gains. By Gauss properties of the interference, the mathematical expressions of the Multiple Access Interference (MAI), Inter-cellular Interference (ICI), Signal to Interference plus Noise Ratio (SINR) and BET are given, and Monte Carlo simulation method is provided. The simulation results show that the theory and computer simulation method proposed in this paper are effective and feasible.

Key words: communication technology, multiple access interence(MAI), inter-cellular interference(ICI), diversity, bit error rate(BER)
