摘　　要：正弦调频键控是一种非单频波带通调制方法,正弦调频通信系统可以实现较高服务质量的无线通信,具有较好的多普勒频移抑制能力,因此适用于高速移动环境下的无线通信系统。本文针对无线信道适应能力,对正交正弦调频通信和目前LTE上行传输链路的单载波频分复用(SC-FDMA)通信系统做出性能比较分析。Sinusoidal frequency modulation keying is a new kind of non-single frequency wave band pass modulation method, and the communication system composed of this kind of modulation with a stronger Doppler frequency shift suppression ability that can achieve a higher quality of service, it is suitable for high-speed mobile environment. In view of the adaptabilities of wireless channel, comparison of system performance between the orthogonal sinusoidal frequency modulation and the LTE uplink transmission single carrier frequency division multiplexing （ SC - FDMA ） are analyzed in this paper.
