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...
Millimeter-wave radar has attracted much attention as a replacement of some infrared or laser systems currently in use. In this paper, an approach of developing high performance waveform for full-coherent millimeter-wave radar is proposed. With good frequency configuration and optimal utilization of DDS (direct digital synthesizer), PLL (phase locked loop) and FPGA (field programming gate array),...
