摘要
MC-CDMA是一种能够有效消除符号间干扰、具有良好抗噪声性能、并能实现高速数据传输的频域扩频技术。文中首先给出一种MC-CDMA信号模型和该模型下的三种检测合并方案:等增益合并方案、最大比合并方案和正交恢复性合并方案,接着对其抗加性高斯白噪声和抗多址干扰性能进行了分析并得出结论,最后通过仿真实验证明了该结论。
MC-CDMA is a effective frequency-spread technique that can realize high speed data transmission, mitigate the ISI and is robust to noise. MC-CDMA signal model and the three data detection methods, i.e., EGC, MAR and ORC, are first provided, then the performance in AWGN channel and ocurringMAI is analyzed and a conclusion is given. Finally, the simulation results that prove the conclusion are described.
