A 128/256-point pipeline FFT/IFFT processor for MIMO OFDM system IEEE 802.16e


In this paper, we present a novel 128/256-point FFT/ IFFT processor for the applications in IEEE 802.16e based on MIMO-OFDM. The pipeline FFT architecture is proposed to efficiently deal with 1–4 multiple data sequences, and increase the throughput. Furthermore, less hardware complexity is needed in our design compared with conventional individual parallel… (More)
