This paper proposes a demodulation and decoding scheme,which combines multiple symbols differential detection with soft-decision decoding.

A frequency-offset correction two symbol differential detection algorithm for multi-array CPM Signals in microwave communication is presented.

Among various demodulation techniques of CPFSK,multiple differential detection(MDD) strategy exhibits even better BER performance than coherent detection,however,its hardware complexity is very high.

Time-frequency differential encoding and detection for cyclic prefix assisted CDMA system;

A novel differential detection method, called Two-Dimensional chip-level differential detection (2D-CLDD) is proposed, the chip-level differential detection is performed in both time domain and frequency domain in two dimensional spread spectrum system, and the channel s fading effect on both time domain and frequency domain can be decreased in 2D-CLDD.

A numerical method for calculating truncated union bound of symbol error rate (SER) is presented for maximum-like- lihood (ML) multiple symbol differential detection (MSDD) over continuous channel in unitary space-time modulation systems.
