Abstract: OFDM is one of the most important technology for high data rate wireless newlinecommunications due to its robustness to frequency selective fading, high spectral newlineefficiency, and low computational complexity. OFDM can be used in conjunction with a newlineMultiple-Input Multiple-Output (MIMO) transceiver to increase the gain of the system newlinecapacity also. Because the OFDM system effectively provides numerous parallel newlinenarrowband channels, MIMO-OFDM is considered a key technology in emerging highdata rate systems such as 4G. OFDM has been adopted in many wireless standards such as newlinedigital audio broadcasting (DAB), digital video broadcasting (DVB) and a potential newlinetechnique for fourth-generation (4G) mobile wireless communication systems. newlineOne of the disadvantages of OFDM is that it has a high peak-to-average power newlineratio (PAPR). This means that the output amplifier at the transmitter has to be linear over newlinea large dynamic range. Linear amplifiers are not efficient, and so increase the power newlinerequirement of the transmitter. This is a major disadvantage in high power applications newlinesuch as broadcast television and in battery operated applications such as Wireless LANs newlineetc. newline
