Abstract
Orthogonal frequency division multiplexing (OFDM) is a popular method for wireless transmission of data at high rate. To increase the speed of transmission, the input high rate data stream is divided into many small data streams which are then transmitted parallel in OFDM system. The key component of OFDM system is the FFT processor. FFT converts the input time domain signal into frequency domain at the receiver side. Efficient implementation of FFT processor with small area, low power and high speed is very important. This can be achieved with the help of various algorithms viz. radix-2, radix-4, radix-8. FFT processor with higher mixed radix (radix-8 and radix-2) algorithm is going to propose. As higher mixed radix algorithm reduces power and increases speed. This paper gives an overview of the work done on FFT processor previously.
