Hello, As the title says, I'd like to know if it would be possible to recover symbols from a transmission containing regular bursts separated by noise (TDMA), using just blocks present in GNU Radio (or some custom algorithm that can be implemented as a block).
I've tried using the correlation estimator together with the symbol synchronization block, but the problem I had was that the known synchronization sequence is placed in the middle of the data burst (as in most such real life transmissions). This meant that the "time_est" tag will not jump start the symbol synchronizer in time to recover all symbols of the burst. What is even worse is that not all data bursts have an embedded synchronization sequence, so there is no way to estimate the difference from expected to actual sample rate until the next sync sequence is transmitted (every 6 frames). Is there a way to overcome this apparent limitation of the corr_est + symbol sync combination? Thank you, Adrian
