Research on Technique of Modulation and Demodulation with Gaussian Minimum Shift Keying(GMSK) ( GMSK ) in Shortwave Frequency-Hopping System 短波跳频GMSK调制解调技术的研究
With the advantages of good spectrum utilization and power efficiency as well as noncoherent demodulation can be employed, GMSK ( Gaussian Minimum Shift Keying(GMSK) ) has been widely applied in the wireless system. 高斯最小频移键控(GMSK)(GMSK)具有极好的频谱利用率、功率效率和可以采用非相干解调等优点,已经广泛应用于无线通信系统,尤其是移动通信领域。
Similarly, as a way of continuous phase modulation with constant envelope, GMSK ( gaussian minimum frequency shift keying ) has good spectrum characteristics and ber performance. 同样,GMSK(高斯最小移频键控)作为一种恒包络连续相位调制方式,它有着优良的频谱特性和误码性能。
