phase coded signal的用法和样例：
例句
- In communication of deep space, the receiving of low signal-to-noise and multi-address communication can be realized with pseudo-random code signal.
深空通信中，利用伪随机编码信号可实现低信噪比接收和多址通信。 - Although the algorithm is lossy, the ear can not feel the quality descension of the encoded audio signal, which means the algorithm is lossless in the perceptual field.
所以，尽管该方法是有损的，但人耳感觉不到编码信号质量的下降，在此意义上我们认为编码保证了音质的透明性。
