additive_noise_channel
模拟噪声的程序，可以根据需要改写，主要功能是实现噪声模型
(Additive Noise Channel/Additive Guassian Noise Channel is the simplest of all channels. File usage details:
op_channel = additivenoise(input_signal)
mathematical Model:
s(t) input signal to channel (=sig_ip)
n(t)additive random noise process added by channel (=noise_mat)
a(t) attenutation factor , here it is taken as random(=att_fact)
out put signal r(t) = a .* s(t)+ n(t)
an additional file named through_anc is there which shows 2 figures, 1. input signal 2. output signal

Dipole_FD
The plots of the Poynting vector might serve to show which part of the wire is mainly responsible for creating the radiated field. The movie of the modulus, |S|, does not give a clear answer, since at close distances the pointing vector reaches high values along the entire wire. The fact that |S| is high along the entire line just means that energy is shifted between the endpoints and the middle region (electric and magnetic field respectively).
