FPGA Implementation of FFT Algorithm for OFDM Based IEEE 802 . 16 d ( Fixed WiMAX ) Communications

⎯The IEEE 802.16d communication standard uses orthogonal frequency division multiplexing (OFDM). In the widely used OFDM systems, the fast Fourier transform (FFT) and inverse fast Fourier transform pairs are used to modulate and demodulate the data constellation on the sub-carriers. In this paper, a high level implementation of a high performance FFT for… CONTINUE READING
