Abstract :
An analog quadricorrelator demodulator is presented. The short introduction to this demodulator is followed by a discussion about the important DC offsets question. To eliminate this, co-channel performance degrading aspect switches are added to the quadricorrelator architecture. System simulation results show how robust the demodulator becomes with this small modification to the structure.
