Modulation-of-a-signal

贪吃蛇，大家都知道了，这个界面有点粗糙。顺便请问一下axis的 drawmode 设为 normal 　或　 fast 有什么区别。(As we all known, this is the snake game. The GUI isn t very well. By all means, it is not bad to make it by MATLAB.)

Quadrature amplitude modulation (QAM) is a modulation scheme in which two sinusoidal carriers, one exactly 90 degrees out of phase with respect to the other, are used to transmit data over a given physical channel. One signal is called the I signal, and the other is called the Q signal. Because the orthogonal carriers occupy the same frequency band and differ by a 90 degree phase shift, each can be modulated independently, transmitted over the same frequency band, and separated by demodulation at the receiver. For a given available bandwidth, QAM enables data transmission at twice the rate of standard pulse amplitude modulation (PAM) without any degradation in the bit error ratio (BER).
