Hi,
I have another question regarding this. I sunk the output from the Costas
onto FFTsink and got this.

Are the peaks that appear on this the lower and upper sidebands of the data
signal? I am transmitting using benchmark_tx.py (dbpsk).
Thank

Thanks a lot Tom for your help. I now understand how Costas loop operates.
After all the tests that I did following your suggestions I was able to find
the answer for a lot of my unanswered questions.
Thanks again,
Ali

I am using Flex-2400 boards and the received signal is ideally at baseband
which in fact is not possible because, of various factors. Now, we have a
signal that has a center frequency 'fc' which is not 0Hz. Assuming the

Can you
Hi Johnathan and other friends,
I want to use an E/P/L Correlation (for Code synchronization) and Costas
loop (for carrier phase sync) for Direct Sequence Spread Spectrum receiver
based on this. http://img19.imageshack.us/img19/826/dsssrxr.jpg I have a
