With all due respect Mr. Javier Antoran,

I know you must be a busy person and I am extremely sorry for bothering you again and again. However, I had a few questions on my mind and wanted to discuss them with you. If you could clarify them I will be really thankful to you for this act of kindness.

  1. We know the code and the data are modulo 2 added and then BPSK modulated over the carrier right? I have generated subframe data containing 1500 bits in each subframe. Let's say I want to perform DSSS how can I do it? Can I just create 20 copies of the CA code and perform a DSSS with every bit in the subframe data? I am getting a matrix dimension error though
  2. You have added Doppler shift and code phases to the signal. Do we need to add them before the modulation or after modulating the signal?
