摘要
通过使用Simulink和System Generator中的模块搭建系统进行联合仿真,验证了对PM信号使用数字混频正交变换和CORDIC鉴相算法进行解调的理论正确性,并对CORDIC算法鉴相模块进行硬件仿真,证明了其硬件可实现。并通过设计表明System Generator加速和简化了FPGA数字系统的设计。
A system is set up by using modules in Simulink and System Generator and carries out an united simulation to verify the correctness of the theory that the PM signal is demodulated using the digital mixer of the quadrature transformation and the phase discrimination based on CORDIC algorithm. And the hardware co-simulation of the module of the phase discrimi- nation based on CORDIC algorithm proves its hardware implementation. And the design scheme show that the System Generator accelerates and simplifies the FPGA design of digital systems.
