摘要
GMSK是目前在移动通信中较广泛的一种信号,由于它采用高斯滤波,相位调制和部分响应信道,因此属于非线性调制,实现起来一般比较复杂。本文根据GMSK信号的线性近似,给出一种新的实现处理方法,仿真结果表明该方法具有良好的近似程度。
GMSK is a spectrum-efficient modulation signal used widely in mobile communication. It is not linear modulation and not easily generaled because of its phase modulation, Gaussian filtering and partial response signaling properties. A implementation of GMSK modulation based on linear approximation is presented here. Simulation result show that the mothed have good approximation of GMSK signal.
