Abstract
According to one embodiment, a demodulation system, such as DPSK in a SPS system can be used with soft decision information to correct bit errors. Soft decision information values are utilized to switch hard decision bits of the differentially decoded signal. A parity check can be used to determine if the toggling of the bit corrected the parity error.
