Thanks a lot for the response Marcus! As the correlation is done only at the decoding level in Gr-802-15-4, the received data is mapped to one of 16 symbols to decode as 0x0 to 0xF.
As seen in the attached file, I'm trying to recreate a collision in the simulation environment by feeding two signals into an add block.
However, when the collision happens, I only receive 0x00 as the symbol for the decoder which does not correspond to any symbol. My understanding is that the collided packet can be obtained if a known original packet is subtracted and decoded from the collided signal.
Since the collided signal received is zero, I'm unable to decode any symbol. Please advise if I'm missing anything.
Thanks in advance.
Best Regards,
Nitin.
