This paper is a survey regarding the orthogonal frequency division multiplexing. The requirement for high speed data transmission has increased, with the rapid growth of digital communication in recent years. UWB delivers much potential for design of high speed wireless communication system. MB-OFDM (UWB) offers high data rates access for wireless communications. OFDM system is use for high speed applications. Modulation and demodulations of signal is done with the help of IFFT/FFT controller respectively. OFDM is one of the efficient solutions for implementing high speed data transmission for wireless communications.
