The use of the soft decision bits to improve the demodulation of the Sps data dpsk

摘要

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