hello sir,
This is vinay, I have purchased your latest book on digital communications using matlab 2nd edition , can you please write a code a matlab code on the following.
1)BER of QPSK over rayleigh channal
2) BER of QPSK over rician channal.

Hello sir,
Is there any book have a complete simulations about femtocells and the interference between the femtocell and the macro cell?

In reply to Mathuranathan.

do u have any idea how can i make a cyclic pn code using the pn sequence generator in simulink
iam facing a lot of problem while iam trying to shift the code to create a new code from it
if u can help me plz ill be thankfull

In reply to Abdallah Kataya. Yes, you can choose the same pseudo random sequence. But the difference is , in CSK cyclic shifts of the pseudo random sequence are used to modulate the data. K bits of input data are modulated using one of the cyclically shifted version of the pseudo random sequence. Actually it combines a form of M-ary orthogonal signaling and DSSS

In reply to Mathuranathan. Do u mean than the code of DSSS is the same for csk ?

In reply to abdallah.

Code Shift Keying (CSK) is a modified Direct Sequence Spread Spectrum (DSSS) scheme. A simple google search will fetch the matlab code for DSSS.

Implementation details for CSK can be found here.

hello sir i want to ask u if u have any code using matlab or simulink about code shift keying modulation
i have been searching for any refrence or code about this type of modulation but could not find anything so plz can u help ?

In reply to Isyaturr Raziah. Sorry, I dont have the code right now. However, it is not tough to figure this out from Matlab's communication toolbox documentations.
