I wish to retrieve data from a BPSK signal, using a digital approach under ATMEL.
This signal is the feedback from a MÃ¤rklin decoder used in model railway. Carrier frequency around 52kHz. Bit duration 912uS.
I whould like to know if any one as implemented BPSK demod on an ATMEL or know how this could be done.
A way is using a Costas loop, an other one is with "the optimal bpsk demodulator with a 1 bit a d front end".
