Re: [Discuss-gnuradio] Measure BER

Hi! I’ve started performing modulation and demodulation on the same machine but the main purpose is to make them work separately afterwards. I’ve seen some BER values on the forums and I was wondering if an “official” block had already been developed to measure it. 1) Tom, May I please have a

Hi all, I'm currently working on a GSMK modem, and I would like to calculate the BER of the link. I send data using gr.vector_source_b( ) connected to a GMSK modulator/demodulator and receive the signal in gr.vector_sink_b( ). 1) How can I measure BER from the vector_source and vector_sink ? 2) Do
