最大似然序列检测技术被广泛应用于数字通信系统中来估计通过有噪声的符号间干扰（ISI）信道传输的数字数据序列。
Maximum likelihood sequence detection (MLSE) is broadly use in the digital communication system to estimate the transferred data through the ISI channel with noise.
为了测量受噪声和谐波干扰的两个信号间的相位差，基于自适应带通滤波器(abf)和测量信道交换技术，提出了一种新的测量方法。
To measure phase accurately in the presence of harmonics for both noisy input signals, a technique based adaptive bandpass filter (ABF) and the method of interchanging signal channel is presented.
仿真结果表明，在AWGN加性高斯白噪声和相关瑞利衰落信道下，系统性能均有显著改进，并能有效克服GMSK信号所固有的严重符号间串扰ISI。
Simulation results show an evident improvement in AWGN and correlated Rayleigh fading channels. The severe intersymbol interference (ISI) of GMSK signals is also effectively suppressed.
