Abstract: When sampling period is very low or close to ideal case for signal detection in additive Gaussian white noise (AGWN), the detection circuit with matched filter is optimal. Otherwise, a bi-stable nonlinear system can be connected to the matched filter, and by adjusting the system parameters, the system will keep in single state for the detection of binary or multinary code, so that the detection performance can be remarkably improved in a wide range of sampling period. In addition, a theoretical formula of the system performance was derived.

Key words: information technology, signal, bit error rate, single stable state, matched filter, correlation
