Abstract

The dynamic selection of guard interval in orthogonal frequency division multiplexing (OFDM) based wireless local area network (WLAN) systems is described in this work. It derives an algorithm and provides its performance merit for implementing variable guard interval (VGI). The proposed system improves mean, outage and maximum throughput significantly as compared to standard OFDM system using fixed guard interval without sacrificing bit error rate performance

基于OFDM的无线局域网可变保护间隔

研究了基于正交频分复用(OFDM)的无线局域网(WLAN)系统中保护间隔的动态选择问题。推导了一种实现可变保护间隔(VGI)的算法，并给出了其性能优点。与使用固定保护间隔的标准OFDM系统相比，该系统在不牺牲误码率性能的情况下显著提高了平均、中断和最大吞吐量
