符号比标记更难理解和解释，因为与信号和标记不同，符号是与个人对世界的不断感知交织在一起的。
Symbols are more difficult than signs to understand and to define because, unlike sings and signals, they are intricately woven into an individual's ongoing perceptions of the world.
系统的输出信号的偏振度还随着信号原始啁啾系数绝对值的增大而减小，但与啁啾系数的符号无关。
And it decreases also with the increase of absolute value of the initial pulse chirp coefficient, but has no relation with the sign of chirping coefficient.
现代短波通信系统，其信道大多数具有频率的选择性，多径传输产生了信号的相干衰落与符号干扰。
In modern shortwave communication systems, the channels are mostly frequency-selective, multipath transmission causes the coherent attenuation and symbol interference.
仿真结果表明，与传统的译码方法相比，新方案对于克服GMSK信号所固有的严重符号间串扰(ISI)有明显的改进。
Compared with traditional decoding method, simulation results of the new scheme show evident improvement in overcoming the severe intersymbol interference (ISI) of GMSK signals.
与数据符号中的导频信号联合进行估计，从而能跟踪信道的变化，进一步提高信道估计的性能。
It carries on the estimation jointly with the pilot signal of the data symbols, so that it can track the changes of the channel to further enhances the channel estimation performance.
