Abstract :
System performance can be improved when channel state information is fed-back to the transmitter, and multiple-input multiple-output (MIMO) systems can realize eigenbeam-space division multiplexing (E-SDM). Pseudo E-SDM offers both reduced complexity (the mean number of multiplications is reduced to about 1/10 for 4×4 MIMO) and a reduction in the effective channel delay spread compared to E-SDM. This work describes a real-time MIMO orthogonal frequency division multiplexing (OFDM) system based on the IEEE802.11n standard. A channel emulator developed using the modified Jakes model provides the fading channels to appraise the algorithm.
