QPSK 的星座图仿真 有仿真信噪比为0dB，10dB，20dB的时候的星座图。(QPSK constellation diagram simulation the simulation signal-to-noise ratio of 0dB, 10dB, 20dB when the constellation diagram.)

programmed to manipulate the Gray Cyclic Binary Codes.

matlab函数scaleif，用于改变度量，详见英文描述( function sim = scaleif(im, newMin, newMax, oldMin, oldMax) Scales an image such that its lowest value attains newMin and it highest value attains newMax. OldMin and oldMax are not necessary but are useful when you don t want to use the true min or max value.)
