Abstract(in English) | This report presents a VLSI architecture of 128-point FFT in a 8x8 MIMO-OFDM receiver. A pipeline FFT processor based on multi-path delay commutator(MDC) architecture is effective for 4x4 MIMO-OFDM systems. To achieve the communication of more high speed and large capacity, it is necessary to design the FFT processor corresponding to the MIMO-OFDM receiver that increases the number of streams. In this paper, we propose the FFT processor to apply the MDC architecture for 8x8 MIMO-OFDM systems. The proposed FFT processor uses the pre- and post-commutators instead of delay elements and improves area and power efficiency. The designed circuit has been implemented to a 90-nm CMOS process and evaluated in circuit area and power consumption. |
