【摘要】 本文在文献提出一种数字MSK调制解调模型基础上,将数字MSK调制技术应用到双工复接通信系统中。采用状态机的方式实现编帧和解帧,在编帧中插入帧头、特殊标志位,解帧过程去掉帧头和帧特殊标志位。用Verilog HDL语言进行模块设计与时序仿真,并在FPGA硬件上实现本设计。设计结果表明基于数字MSK调制的双工复接通信系统在实际应用上是可行的。更多还原

【Abstract】 The paperputs forward a new model for digital MSK modu1ation and demodulation based on with a digital carrier, this paper applies the digital MSK modulation technology to the full duplex multiplexing communication system. It implements encapsulation and recovers the data from encapsulation in the deframer using state machine, inserting synchronization flags and special flags in the process of encapsulation. Then taking out the flags in the deframer. It carries through module design with Verilog HDL and timing simulation, and achieves in the FPGA hardware. The design results of digital MSK modulation technology indicates that the full duplex multiplexing communication systems is feasible in actual application.更多还原
