The generation of pwm baseband digital signals and the demodulation 基带数字信号的产生与检测
The single dsp can transmit baseband signal to digital up converter and receive baseband sample signal from digital down converter through the control of interrupt signal at the same time . the stability and reliability of complete digital transmission system can be realized by this way 本文利用dsp的中断控制,在单片dsp内发送基带数字信号同时处理来自数字下变频器的基带数字信号,实现了稳定、可靠的全数字中频与基带传输系统。
Considerable research fruits have been achieved in the field , and a few companies in home and abroad have invented the military digital radios . a certain communication company stimulated by market competition and the demand of the current vhf ( shorted by " very high frequency " ) radios " digital transform , established the " zx08 " project so as to conduct researches on the if digital and base - band digital signal process 软件无线电方面,国内外已有许多研究成果,国内外公司也已研制出数字化的军用电台,国内某通信公司顺应市场竞争要求,针对当前超短波军用电台数字化转型的需要,成立编号为“ zx08 ”项目,展开中频数字化、基带数字信号处理研究。
