additive Gaussian channel的用法和样例：
- The simplest, yet very useful method for detecting a known deterministic signal in additive Gaussian noise is matched filter(MF).
- When sampling period is very low or close to ideal case for signal detection in additive Gaussian white noise (AGWN), the detection circuit with matched filter is optimal.
- A new feature based on higher order statistics is proposed for the classification of MPSK signals, which is invariant with respect to constellation translation (shift), scale and rotation, and can suppresses the color or white additive Gaussian noise.
- First,based on the Viterbi algorithm and the Least-mean-square(LMS) algorithm,the computer simulation of digital communication system with ISI and additive Gaussian noise has been made,by means of the adaptive-decision-feedback equalizer.
