I have a question applying to everybody that have tried transmitting symbols in different kinds of modulation (BPSK, QPSK, GMSK etc). I am using the following configuration in GNU Radio ( random source block -> bytes to symbols -> SRRC block -> file sink)
The attached figure plots the generated symbols (+1,-1) with red color along with the upsampled SRRC waveform (blue) For some reason that I am not able to understand the last 8-bits do not have a correspondence with the waveform created. In other words
the waveform is "cut" at the last byte. Can anyone help me with the above.
