仿真4-PAM（脉冲幅度调制）载波调制信号在AWGN（加性高斯白噪声AWGN(Additive White Gaussian Noise)）信道下的误码率和误比特率性能，并与理论值相比较。-Simulation 4-PAM (pulse amplitude modulation) modulation signal in AWGN (additive white Gaussian noise AWGN (Additive White Gaussian Noise)) under the chan

数字基带信号的仿真包括双级性信号、单级性信号、pam信号在AWGN信道的仿真-Simulation of digital baseband signal includes a signal of a two-stage, single stage of the signal, pam signal simulation in AWGN channel

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.
