So if you are concerned about the bandwidth you are transmitting- then this is the reason to reduce it, otherwise you're not far with what you have to make the receiver work. | |
Apr 15 at 10:56 | comment | added | mr_js | Thanks for your comprehensive input. I'm actually aware of the Costas loop and other techniques. My problem is getting them to work on non-ideal signals. Reducing the bandwidth by not transmitting square waveforms should be a help. In this case, raised cosine filters are more relevant... | |
