OFDM-STBC Based Transceiver for WiMAX 802.16e


The development of 802.16 standards for Broadband Wireless Access technologies(BWA) was motivated by the rapidly growing need for high-speed, ubiquitous and cost-effective access. The limitations of conventional Broadband wireless access have been overcome with the scalable features of WiMAX.WiMAX is Worldwide Interoperability for Microwave Access (WiMAX)[5].It is one of the wireless communication technologies, especially Broadband Wireless Access (BWA) which uses OFDM and MIMO systems in order to provide high data rates, minimization of bandwidth and fading effects. Orthogonal Frequency Division Multiplexing (OFDM) is one of the best digital modulation schemes, where signal is divided into number of narrow band channels to obtain spectral efficiency and minimizing the Inter Symbol Interference (ISI)[2].In this paper we have reviewed the communication system of OFDM-STBC based transceiver for WiMAX 802.16e standard
