A novel weaken signal detecting and frequency estimating blindly algorithm (LSFD) based on period-time-average is proposed according to the cyclostationary under stronger interference.LSFD algorithm can estimate signal frequency correctly
and restrict interference and noise effectively than FFT.The analysis and simulation results show that LSFD algorithm is blindly
