Can someone please help in calculating the ber?
I think there Is delay mismatch in ref signal port and input signal port so
how to calculate that delay?

Is there a box that can do the BER calculation given the clean input data
bit stream directly from the source and the demodulated data bit stream on
the receiver side?

Hi..
I found the mistake which i was doing in digital_bert_tx.py file.
i was always transmitting 1 but after scrambling when we do packing then
according to this statement
self._pack = blocks.unpacked_to_packed_bb(self._mod.bits_per_symbol(),
gr.GR_MSB_FIRST) in qpsk modulation in place of 1 it wi
Hi everyone,
I am trying to calculate BER for bpsk and qpsk using digital_bert_tx.py and
digital_bert_rx.py. i want to compare BER of qpsk and bpsk. At same SNR
around 20db i am getting constant .16 BER for qpsk and for bpsk it is
1e-12. when i change the SNR using gain of Transmitter and Receiving
