Hi Tom,
Thanks for your answer. That's indeed something that I need to think about more. However, as I understand it, the samples per symbol rate is equal to (samp_rate / data_rate). My sample rate is 500k, and my data rate (i think) is only around 100 or 200. See this figure of my (cleaned) signal: http://imgur.com/8pNqCop You see that it takes approximately 10 ms to transmit one symbol. This means 100 symbols per second. As I have 500k samples per second, this means 5k samples per symbol, right? However, I have tried setting the samples per symbol to 4, just to try, and the 'out of bounds' error still persists.

Michael, I don't have an answer, but I can say where you're doing something wrong. You're samples/symbol (samp_per_sym) is definitely /not/ 2.5k. That's a massively oversampled signal and can't be right. You need to think what's the sampling rate of the system? What's the symbol rate of my signal? That will tell you the samples/symbol you need. It should small, like 2 or 4. Tom |
