最小频移键控(MSK)是一种性能较优的数字调制。本文叙述MSK信号的三种产生方法之间的关系、MSK信号功率谱以及MSK信道的计算机模拟。文中根据系统的方块图导出系统的基带等效模型,在不同的信道带宽和硬限幅条件下,模拟对系统误码率的影响。
Minimum frequency shift keying (MSK) is a better performance digital modulation. This article describes the relationship between the three generation methods of MSK signals, the power spectrum of MSK signals, and the computer simulation of MSK channels. In this paper, the baseband equivalent model of the system is derived according to the block diagram of the system, and the impact on system bit error rate is simulated under different channel bandwidths and hard clipping conditions.
