Jian Wang · Computer & Network · 2010
This paper presents a practical blind non-cooperation weak signal detection technology based on research of different features of background noise and target signal,and makes theoretical analysis for new detection technology and describes algorithm process.The simulation and analysis are done for multi-signal detection performance in complex EM environment and single-signal detection performance in low SNR environment.The simulation results show that the new detection method can be used to obtain better detection and estimation accuracy for different wireless signals in white Gaussian noise channel,and has such features as low computational complexity,high precision and easy-to-hardware implementation.
