摘要

提出了一种基于接收窗(RW)的移动OFDM解调技术。首先利用rw将OFDM块分割成多个不重叠的区间，然后提出一个加权组合来补偿带窗块间的信道时变。RWs的优化设计考虑的是最大化信噪比。理论分析和仿真实例均表明，该方法优于传统的解调方法。

A Demodulation Technique for High Mobility OFDM Systems

This paper presents a receive windowing (RW) based demodulation technique for mobile OFDM systems. With the aid of RWs, we firstly split an OFDM block into non-overlapped intervals, and then proposed a weighted combination to compensate for the channel time-variation across windowed blocks. The optimal design for RWs is considered with respect to maximizing the signal-to-interference plus noise ratio. Both theoretical analysis and simulation examples illustrate the superior performance of our method over the conventional demodulators.
