1. ### Help: Wireless Communication course by Tse at Berkeley

Hello! Is there anyone who has the education material for the course "Fundamentals of Wireless communication" held by David Tse at Berkeley in 2004 spring? The link is the following, but the access is denied (even when using proxy server): **broken link removed** I'm in great need of this, as...
2. ### How to calculate the impulse response values?

Channel model question Hello! I'm given the following plot. I know that the sampling frequency is 8Khz (speech). I have to calculate the impulse response values for my matlab simulation... Please help me how to do this, thank you in advance, regards, Thommer
3. ### Channel environment, impulse response question

Hello! I have implemented in matlab some classical channel equalization methods (I used AWGN,BPSK). I have to make BER vs SNR simulations and should do this in different channel environments (rural, hilly, urban..etc). I'm looking for the corresponding impulse response values for them, but so...
4. ### Simple matlab question (matrix->vector)

Hello All! I have a probably primitive problem, but please help me! I have a matrix (arbitrary), I want each row of this matrix to be in a separate vector. eg: y=[ -1 1 -1 -1 1 -1 1 -1 -1 1 1 -1]; I tried the following: t = reshape(y',1,[]) -> [-1 1 -1 -1 1 -1 1 -1 -1 1...
5. ### How to calculate the theoretical BER?

Hello! I have an AWGN channel model (for single user) The noise is: nu~N(0,sqrt(N0)) 0 mean and sqrt(N0) standard deviation, where N0 is the noise energy. In my case SNR=1/N0. How can I calculate the theoretical Bit error rate? Thank you Thommer
6. ### MMSE equalizer for MATLAB

mmse equalizer Hello! I'm looking for MMSE equalizer matlab code for AWGN channel model , single user mode. Thank you in advance, Thommer
7. ### Steepest descent in matlab

matlab steepest descent Hello, I have a function which contains sums and a normal distribution as well.As I read the Matlab tutorial, for finding the gradient is better to use the conjugate gradient method, but I have to solve this with the steepest descent method. Is there any built in...
