在MATLAB中编一个2FSK调制的信号，可以用类似方式产生2psk信号等等其他调制信号-A 2FSK in MATLAB code modulated signal can be used to produce a similar manner 2psk modulation signal, and so other

OFDM simulation system use different modulation technique such as M-PSK M-QAM user can select that type . the program use image to be transmitted in QI mapped ,signal affected by AWGN and Fading on channel be for received
