Hi There, I basically have two questions. 1. How do I specify the Symbol Table in the Chunks_to_Symbols block? 2. How do I M-QAM (M = 8 / 16, etc) modulate data from the audio sink (speech)?
For the second part, I thought of the following setup: Audio Source -> low pass filter + decimation -> float to char -> Unpacked to packed -> chunks to symbols -> root raised cosine filter -> USRP Will this work for a very basic and simple setup? Kind Regards, Jaco
