I have a M file with the codes of my channel transfer function. My transceiver model however is built in Simulink. Is there a way to simulate my transceiver with my transfer function without any S-function programming? I'm close to my due date and this instruction was given to me last minute by my instructor. Please advise. Thank you.

Hi, I would be grateful for any helpful comments on this. I am a beginner at using the Comms blockset in Simulink, and have tried just putting a signal through DQPSK modem system, with just AWGN in between. When I stick a BER detector at the end, the result seems to depend on

Hi all, I am a new member, I am trying to use simulink to perform denoising on a vector signal. I tried to use the wavelet function WDEN (it is included in the wavelet lib in the toolbox). The output of the s- function block is the same as the input signal. I guess the problem

Hello, I'm trying to learn how to use Simulink and I'm trying to modify the dvb-t demo. I don't understand why the Ts of the source is computed as Ts=0.000224*2176/9072/188 . For sure I know that it depends from the mode (2k) and the mapping used (64-QAM), but I can't understand why is computed in this way. Could you make an example (i.e. mode 8K,16-QAM). Thanks Riccardo ps: this is ...

Hi all! I'm a completely newbie in DSP's subjects, and I have to develop a Adaptative Noise Canceller using it! I've chosen the C6713 DSK because it has 2 inputs for both microphones that I pretend to use and also the matlab support. I don't know very much C. Firstly, had anyone already done that? I'm having a problem to make the 2 inputs (LINE IN and MIC) work together in Simulink. It s...
