碩士 === 龍華科技大學 === 電子工程系碩士班 === 101 === In this research, we design a digital chip module that are aimed at the processing of TDMA signals which were applied in wireless communications. In this TDMA subsystem, 64 separate sensors (transmitter, Tx) will transfer the signals taken from ADCs to one base-station (Receiver, Rx) via the wireless channel. A physical layer specification is proposed for this TDMA subsystem. In this specification, the base-station will transfer the pilot signal to 64 sensors and receive the signals taken from 64 sensors. The pilot signal provides the sources for synchronization for each sensor. The base-station collects these 64 sensors signals and passes them to the upper layer DSP, via a qusi-UART interface, for further processing. The maximum sampling rate for each sensor is 4.813kHz and the clock frequency is 4MHz in our specification. The base-station module is designed and tested by FPGA/Synopsys/Cadence toolkits and its performance is listed.
