摘要
本文给出了一种修改的数字调相信号的调制解调器、电路设计新颖、实现简单。并对这种修改的数字词相信号的功率谱进行了分析。与普通调相(PSK)信号的功率谱比较表明,修改的PSK方式在频谱利用率上优于PSK方式。
In this paper a modem of modified phase shift keying is given.The design isnew and The circuit is simple. The power spectral density of modified phase shift keying isgiven. Compared with the power spectral density of phase shift keying, its spectral utiliza-tion ratio is higher than spectral utilization ration of phase shift keying.
