Abstract: This paper analyzes the effects of fixed point Fast Fourier Transform (FFT) computation in Orthogonal Frequency Division Multiplexing (OFDM) for Wireless Local Area Network (WLAN) application. The performance of WLAN has been investigated using Matlab simulations under Additive White Gaussian Noise (AWGN) channel for different modulation schemes. The simulations carried out here, show the effects of fixed point FFT on the performance of OFDM used in wireless LAN. Extensive computer simulations show that fixed point computation provides very near result as floating point if the delay parameter is suitably selected.
