Channel Model Block in GNU radio

Hi,

I am working on the channel model block in GNU radio. I am confused in
setting up the taps.I have a random source that undergoes a QPSK
modulation
at 4 samples per second.Could you please explain me the concept under
setting the tap values.

I am supposed to use a polyphase clock synchronizer followed by a CMA
equalizer for analyzing the channel response.

Looking forward for your reply.

Thanks
Merry

Hi Merry,

the taps characterize the channel you want to simulate, so you will need
to calculate these based on your mathematical channel model. The
classical multipath channel model is a tapped-delay line-model, and that
kind of directly maps to the concept of filter taps.

Are you sure you do 4 samples per second? That seems to be incredible
little, especially when working with channel impulse responses.

Greetings,
Marcus
