Abstract :
Non-coherent signal with unknown delay and Doppler is recovered by Gabor Division/Spread Spectrum System (GD/S3) with bipolar data. Separable Property (SP) condition for time and frequency synchronization leads us to determine phase correction terms in GD/S3 receiver. The receiver of GD/S3 is applicable for MPSK communications by introducing equation phase-tuned layers (for k = 1, 2, ..., M)1).
