Implementation of the TDD system baseband data processing based on FPGA

TDD is one of the duplex technologies used by the mobile communication system, and its role is to separate the receiving and transmitting channel (the uplink or downlink). This paper presents a high speed TDD baseband data processing system realized on the FPGA. Through the data transceiver loop method, it's verified that the transceiver switching rate of the TDD mode can be 8KHZ and the data transfer rate can be 120 Mbps.
