摘要：

This paper presents the practical implementation of digital predistortion (DPD) for power amplifier along with the transmitter and receiver diversity techniques for multiple inputs multiple outputs (MIMO) communication to enhance channel capacity and increased coverage. The MIMO diversity techniques are implemented in a Xilinx Zynq 7000 FPGA to drive wideband RF transceiver AD9361. In addition, DPD is applied to compensate for amplifier nonlinearity in each MIMO branch for 4G, 10 MHz LTE signal.
