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

- Function to generate Walsh Code
- License: Freeware
- Price: 0.00


This function generates Walsh Codes. The difference between this function and other functions available to generate walsh code is : 1. you can call this function directly in your script, you will have to pass only the value of 'a' (length of code is 2 ^ a) 2. this function can return you both the walsh matrix and randomly selected row (you may need just one sequence for your script) for usage details refer to file. syntax: var = walshcode(x) x = (0, 1, 2, 3, 4, ....) ==> length of code y = 2 .^ x = (1, 2, 4, 8, 16, ....) by default the var will be a matrix (y x y) for getting any one sequence go to the file and invoke another built in function by removing '%' (refer file)
