利用传统方法及MUSIC方法估计信号DOA，其中阵列为ULA(Use of traditional methods and MUSIC methods are used to estimate the signal DOA, one array for the ULA)

说明：  设基带码元传输间隔为0.1秒，FSK调制参数分别设置频率间隔为5Hz和20Hz，相位分别设置为不连续的和连续的两种。试对比观察4元FSK调制输出等效低通信号的功率频谱。(Let the baseband symbol transmission interval is 0.1 seconds, FSK modulation parameters are set the frequency interval of 5Hz and 20Hz, respectively, set to the discontinuous phase and continuous two. Observation of test 4 yuan FSK modulation output equivalent low pass signal of the power spectrum.)
