Reduction of ICI in MIMO OFDM by self-cancellation technique with FFT

Increasing speeds and complexity of wireless communication systems have necessitated the progress and advancement of high performance signal processing components. Today's developing technologies involve fast processing and efficient use of properties. These properties include memory, power, and chip area. 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. Ongoing research seeks to optimize resource usage as well as act. Design develops a balance and trade off flexibility, performance, difficulty, and budget. In this paper, it specifically address the power-efficient design of an FFT processor as it relates to emerging OFDM communications. OFDM is one of the efficient solutions for implementing high speed data transmission for wireless communications.
