抄録: When channel state information is fed-back to the transmitter, multiple-input multiple-output (MIMO) systems can realize eigenbeam-space division multiplexing (E-SDM) and system performance can be improved. Pseudo E-SDM offers both reduced computational complexity (the mean number of multiplications for 4×4 is reduced to about 1/10) and a reduction in the effective channel delay spread compared to E-SDM. This work describes the design of such a MIMO orthogonal frequency division multiplexing (OFDM) system based on the IEEE802.11n standard. The paper describes the real-time processing on field programmable gate arrays (FPGA) capable of sustaining a maximum 260 Mbps service within a 20 MHz bandwidth and the MIMO signal processing computed on digital signal processors (DSP). The modified Jakes model permits the Rayleigh fading channel to be emulated in real-time with limited hardware complexity.
