Abstract
To overcome the problem of inverse π of 2PSK(Binary Phase shift keying), a new kind of non coherent demodulation for 2PSK was proposed, and the principle and noise resistance of the system was analyzed. Non coherent demodulation for 2PSK detects relation of carrier wave phase of the interval symbol by the (half period of carrier wave) delay and the adder, then the data is demodulated. The demodulation technique has some strongpoint such as high capability in intrinsic error detection and noise resistance and easy implementation.
