This PR improves the performance of the channel processing.
It made faster by 270x in the function getChannel and 23x in the function applyChannel than the current version on my computer.

The main changes:

  • getChannel: generate CIR by matrix operation without for-loop.
  • applyChannel : process the time-varying convolution in different functions in order to get optimization of the for-loop by the Julia compiler.

p.s. thank you very much for creating this wonderful package!!

Dear hassiweb
Thank you very much for this PR. You are completely right, the code dedicated to channel generation was far from being optimized and I really appreciated that you take the time to review my code and propose modifications !
The PR will be merge now and I will update the package reference.

Thanks again !
Robin Gerzaguet
