  • 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
