Abstract :
This paper presents a scalable hardware architecture of multi-input multi-output (MIMO) channel emulator. The basic 4×4 MIMO emulator hardware module is designed and implemented based on Viretex-6 FPGA with 100MHz bandwidth. Complexity and used resource are analyzed. Furthermore, the relative error of fixed-point and float-point simulation are compared for implementation. In particular, this design methodology allows for extending to 4M×4N MIMO channel emulation.
