在matlab上面实现fsk、4fsk、pam等调制解调程序-To achieve the above in matlab fsk, 4fsk, pam procedures such as modulation and demodulation

psk and pam modulation and demodulation with noise

scr ipt for pulse amplitud modulation (PAM) affected by AWGN, the electrical spectrum and the diagram eye is obtained. As well, as BER estimation is performed.
