In Broadband Fixed Wireless Access (BFWA) systems, multipath delay is most detrimental to system performance. Multipath delay will result in intersymbol interference, especially in high data rate applications. Work has been done in predicting delay spread in mobile wireless area. My research is to develop new algorithms and theory to predict the multipath delay in fixed wireless system.
