摘要
为了对中频PCM信号进行直接解调,提出一种全新的数字化PCM中频解调器的设计方法。在实现过程中,采用大规模的FPGA芯片对位帧同步器进行了融合,便于设备的集成化和小型化。这种新型的中频解调器比传统的基带解调器具有硬件成本低和误码率低等优点。
In order to demodulate directly PCM signals,a new design method for the IF demodulator is proposed.Large-scale FPGA chip is used in the process of implementation to realize of the fusion of frame and bit synchronization,which is convenient for integration and miniaturization of demodulators.This new IF demodulator has features of less hardware cost and lower BER than traditional baseband demodulator.
