Hello everyone, I was giving the task of quickly develop a receiver for an old satellite system that use a pulse shaping filter with square wave impulse response and QPSK constelation.
Does GNU Radio has a prompt solution for this? By a prompt solution a mean a single block in GNU Radio Companion that handles carrier phase synch, symbol time synch and sampling. From its documentation its seams to me that it lacks of prompt solution for old fashion square wave pulse shaped signals. Am I right? I have seen that GNU Radio has a prompt solution for demodulating QPSK signals with Squared RRC filter. And I known that it can be used for square wave signals too. However, I want to avoid the performance degradation from not using a matching filter at the receiver end. Any suggestion for a quick solution for my problem? Regards -- José Marcelo L. Duarte
