Design and analysis of cost-efficient IFFT/FFT processor chip for wireless OFDM systems

In this paper, a cost-efficient IFFT/FFT processor with its fixed-point analysis is presented for wireless orthogonal frequency division multiplexing (OFDM) system. The IFFT/FFT processor is multiplierless architecture, and the nonzero bits of twiddle factors (TW) are minimized to reduce the structu...
