Soft MIMO: A software radio implementation of 802.1 In based on Sora platform
Ji Fang, Zhenhui Tan, Kun Tan · 2011
MIMO has been widely used in many wireless communication systems. Due to the high computational and real time processing requirements, many MIMO systems are implemented in ASIC, FPGA and DSP. But they are fixed and cannot be easily modified or upgraded. To deliver a high performance programmable and flexible MIMO system, this paper presents a 2x2 MIMO system based on 802.11n. The system has implemented on multi-core CPU based software radio platform. With parallel processing, both the transmitter and receiver satisfy the real time processing requirements.
