Convolution in MATLAB Simulink

Hello,

I have a impulse response stored in a file impulse.mat. I want to perform convolution in SIMULINK for the continuous input signal(Say input signal coming at at 1Gbps). How can i implement it in Simulink?

Hello,

I wonder how can you generate your impulse response? I need it for my undergraduate thesis that's about feed-forward controller.

Hi Amith, Thanks for your reply. My situation is like this.

My impulse response is stored in impulse.mat file and incoming signal is strings of 1's and 0's at a certain data rate..For this case how can i do convolution in simulink?

So for the impulse.mat file, there is a block called the 'from file' block in the sources listing in Simulink.

Does this answer your question? I'm sorry but I don't have simulink immediately to test the model in the link above.

Thanks for your kind reply. I have one more question

I want to generate 1Gbps PRBS data.I got sequence generator from http://www.mathworks.com/matlabcentral/fileexchange/18434

but can u please tell me how can i generate 1Gbps data???

I'm guessing you have to use the prbs_7bits block, but as for the Gbps part, I don't think there's any way you could simulate that, for it's a discrete process on a simulator. I may be wrong, for this is not really my area of expertise.. I'm sorry.
