基于FPGA的TDMA数字通信系统的设计

The design of TDMA digital communication system based on FPGA

基于EDA技术及VHDL硬件描述语言,提出了一种TDMA数字频带通信系统,在一片EPF10K10的FPGA芯片上完成了位同步、帧同步、A律压缩与解压、FSK调制与解调等系统的大部分功能,实现了4路语音与2路64kB数据全双工通信。

A communication system with TDMA digital frequency band is put forward based on EDA technique and the description language of VHDL.On the FPGA chip of EPF10k10,most functions of the system are accomplished such as the completion of phase synchronism and frame synchronization,compression and expansion of A rhythm,the modulation and demodulation of FSK,implementing the communication with 4-channel audio and 2-channel 64KB data.
