突发通信具有环境噪声大、突发帧短等特点,常规的解调器不能满足要求,文中提出了一种全数字突发信号实现方案,以并行进行位同步、载波同步等加快捕获速度。通过在Xilinx的FPGA上实现,并经工程测试表明,该接收机具有高速传输、捕获速度快等特点,适合高速突发通信场合使用。 Burst communication has the characteristics of large ambient noise and short burst length. Conventional demodulator can not meet the requirements. In this paper, an all-digital burst signal scheme is proposed to speed up the acquisition in parallel, such as bit synchronization and carrier synchronization. By Xilinx FPGA implementation and engineering tests show that the receiver has high-speed transmission, capture speed, etc., suitable for high-speed burst communications occasions.
