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

ttbox25102012
一款利用matlab编写的射线追踪程序，易改易用。(The installation of TTBOX is relatively simple. All you have to do is to create some directories and tell MatLab, where TTBOX is.
if it does not already exist, create a directory matlab within your home directory.
Copy the TTBOX directory into the matlab directory
if it does not already exist, create a file startup.m within the matlab directory
Insert the following lines into startup.m:
basepath= This should be the path to your home directory!
addpath([basepath filesep matlab filesep ttbox ],1)
addpath([basepath filesep matlab filesep ttbox filesep support ],1)
execute startup within the MatLab command window.
MatLab is now ready to execute TTBOX routines.
The startup-script will be executed automatically upon start of MatLab.
In order to read the online documentation, you have to browse to the doc directory and open the ttbox/doc/ttbox.html file with your web browser (it is recommended to set a bookma)
