DS-SS/BPSK Signal Detection With Delay Multiplication Multi-correlation Based on Over-sampling
Jie Zhou · Information and Electronic Engineering · 2006
The DS-SS/(Binary Phase Shift Keyed,BPSK) signal detection approach with delay multiplication multi-correlation is proposed in this paper.The principium of delay multiplication correlation is deduced;the influence on output SNR(Signal to Noise Ratio) relative to delay multiplication multi-correlation based on over sampling is analyzed.The theoretical analysis and simulation show that delay multiplication correlation based on over sampling can recover the carrier of DS-SS/BPSK signal and remains the additive Gaussian white noise characteristic of input noise at the same time;in addition,its output SNR can be increased by passing through multi-correlation detectors.
