基于FPGA的MIMO信道衰落的硬件实现

In this paper a hardware-based MIMO channel fading implementation procedure is introduced. Typical wireless channel introduces a Rayleigh fading to the signal. An improved model of Jakes model is used to generate an exllent performance, and the simulation result, concerning both floating-point and fix-point simulation, proves its fitness on hardware design. An important characteristic of MIMO channel is, fading for different sub-channels may differ from each other. As to a channel with enough scatters, all fadings are supposed to be independent, namely i.i.d. This paper takes the independence into account to provide a solution on modeling MIMO channel on FPGA. In the end, it gives a statistical prove on the performance.
