The Spatial MIMO Channel Implement on FPGA

The MIMO channel simulator for signal transmit-receive system is needed to research the signal multipath effect in mobile environment and the small scale Rayleigh fading channel mathematical model in real hardware environment. The paper designs a pipelining infrastructure on Field-Programmable Gate Array (FPGA) to imitate the stochastic spatial MIMO channel. At the end, some important parameters of MIMO channel, including Doppler spread, angle spread of arrival and departure and channel capacity of different angle spreads, etc, are emulated and analyzed. The simulation results are very close to theoretical values. The pipelining infrastructure is proved to be fit for structure base of the MIMO hardware simulator in experimental environments.
