Chapter 2 Literature Survey 2.1 Introduction 2.2 Reported Work on Fft Architectures

Orthogonal Frequency division multiplexing is a field that is in vogue and the latest mobile communication technologies have exploited the advantages of the technique. There have been a lot of architectures that have been presented to improve the performance of the OFDM system. The OFDM transceivers employ both Inverse Fast Fourier Transform and Fast Fourier Transform blocks. A variety of architectures have been presented for improved performance in OFDM transceivers. Specifically FFT architectures which improve on the throughput and latency have also been extensively researched over the last 2 decades.
