Abstract
This letter presents a new algorithm for improving the Signal to Noise Ratio (SNR) of complex sinusoidal signals contaminated by additive Ga ussian noises using sum of Higher-Order Statistics (HOS). We conduct s ome computer simulations to show that the proposed algorithm can impro ve the SNR more than 7dB compared with the conventional coherent integ ration when the SNR of the input signal is -10 dB.
