7DOF

对正弦信号进行FFT变换 画频谱图，进行频谱分析，可以计算出信噪比(Sinusoidal signals of paintings transform FFT spectrum chart, spectrum analysis, signal to noise ratio can be calculated)

By using these matlab codes one can simulate awgn in any system and cam add it to any signal for further analysis

Rician fading is a radio propagation anomaly caused by partial cancellation of a radio signal by itself — the signal arrives at the receiver by two different paths, and at least one of the paths is changing (lengthening or shortening). Rician fading occurs when one of the paths, typically a line of sight signal, is much stronger than the others. In Rician fading, the amplitude gain is characterized by a Rician distribution.

A cyclic redundancy check (CRC) is an error-detecting code designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. Blocks of data entering these systems get a short check value attached, derived from the remainder of a polynomial division of their contents on retrieval the calculation is repeated, and corrective action can be taken against presumed data corruption if the check values do not match.
