Re: Understanding Pulsed signal Demodulation and decimation in GNU Radio

Hi Isaac, I am not sure what you are trying to achive. However, your low pass filter seems to be set up incorrectly. You have a signal with 1MHz and 10MHz samplerate. Your low-pass filter has a cutoff at 5MHz and then down-samples by 100. If you want to make sure that there are no frequency c

Full Modem Lifecycle Development

GNU Radio - I'm new to GNU Radio and have been impressed with it! It seems like GNU Radio is a block based processing framework and I was interested in using it for modem development. I would normally create a C/C++ simulation all from scratch, but I'd have to build my own modem development environ
