连续相位调制器的FPGA设计

FPGA Design of Continuous Phase Modulator

对连续相位调制信号进行了详细的讨论,在基于整环分解模型的基础上,提出了一种连续相位调制器的FP-GA设计方法;同时给出了一种高效的ROM寻址查询方式,利用该查询方法设计出的ROM芯片的规模是按传统寻址查询方法设计ROM规模的12,这样可以极大地减少CPM系统的成本,具有极大的实用价值。

A detail analysis of continuous-phase-modulation signals using a decomposed model of CPM is presen ted. Based on this analysis, we obtain a method of FPGA design of continuous phase modulator, and a new looking up model in ROM is expressed. With the new technique, only half of the scale of the ROM using the old model is needed. There will be a growing awareness that this new model is of great value.
