摘要
The differential detection system comprises a demodulator for a modulated carrier transmission system for binary signals, in which a symbol detected from the phase difference between the received signal delayed by one signaling interval and the signal received in the present signaling interval is converted into data and a symbol detected from the phase difference between the received signal delayed by two signaling intervals and a signal received in the present signaling interval is converted into parity. The data and the parity are applied to a decoder for a rate 1/2 single error correcting self- orthogonal convolutional code effecting demodulation with non-redundant error correction. The correction system is also applicable to demodulate a carrier wave modulated by m (an integer) level digital data.
