摘要

讨论了多载波码分多址(MC-CDMA)系统上行链路中的信道获取和跟踪问题。采用两种不同的方法进行信道采集和噪声功率估计。前者假设独立衰落的子载波，而后者利用信号带宽上的衰落相关性来提高系统性能。这两种方案都基于最大似然(ML)推理，并利用一些携带已知符号的训练块。信道跟踪是通过最小均方(LMS)技术进行的，使用由部分并行干扰消除(PPIC)接收器提供的数据决策

Multiuser Channel Estimation and Tracking for MC-CDMA Uplink Transmissions

We discuss channel acquisition and tracking in the uplink of a multi-carrier code-division multiple-access (MC-CDMA) system. Channel acquisition is performed jointly with noise power estimation following two different approaches. The first assumes independently faded subcarriers while the second exploits the fading correlation across the signal bandwidth to improve the system performance. Both schemes are based on maximum likelihood (ML) reasoning and exploit some training blocks carrying known symbols. Channel tracking is pursued through least-mean square (LMS) techniques, using data decisions provided by a partial parallel interference cancellation (PPIC) receiver
