： To meet the testing requirement for the industry and society, a remote distributed MIMO channel simulation system （RDMSS） for broadband wireless communication is proposed and designed. After MIMO channel emulation technology requirements are analyzed, a 2X2 MIMO semi-physical hardware channel simulation platform is constructed and optimized by using generic test instruments to achieve the channel simulation and the verification of MIMO channel model. Moreover, RDMSS software is developed. In this system, the channel requests simulation of the remote distributed user are preprocessed and executed, and the results are released. By many remote distributed users＇ channel emulation services, RDMSS is proved to achieve effectively the high performance, multi scenarios, low-cost MIMO channel emulation.
