摘要：The testing of a wireless transmitter and receiver in the real-world channel is tedious. So, a channelemulator using FPGA helps in the testing of transmitter and receiver by providing a test environment thatsimulates a real-world wireless channel. Since FPGAs are flexible, cheap and reconfigurable, they areused in designing an AWGN channel emulator for 4G LTE for Single Input Single Output (SISO) andSingle Input Multiple Output (SIMO) environments. In this paper, three basic modules: transmitter,channel estimation and receiver modules are synthesized. In the transmitter module, the input data is 64-QAM modulated and transmitted into the channel. In the channel estimation module, the transmitter datagets multiplied with the channel coefficients and then added with the noise present in the channel. In thereceiver module, the data is detected using MMSE estimation. These are implemented in Virtex-5 deviceusing PlanAhead tool and the Resource and Power Estimations are discussed.
