INTRODUCTION Orthogonal frequency division multiplexing (OFDM) is now a popular technique for high data rate wireless communication. Due to its simple imple-mentation and attractive performance against fre-quency-selective wireless fading channels, it has been adopted in several wireless standards such as digital audio broadcasting (DAB), digital video broadcasting (DVB), IEEE 802.11a local area network (LAN), IEEE 802.16a metropolitan area network (MAN) and asymmetric digital s…  相似文献
