Signal De-noising in ELF Receiver
LI Zhong-jia · Journal of Wuhan Institute of Shipbuilding Technology · 2008
Based on the ELF received signal model,bit error rate of it be analyzed.Wavelet de-noising algorithm is applied in noise processing.By Monte Carlo computer simulation,noise buried in ELF signal is dealt with wavelet de-noising and traditional digital filter.Its quality of bit error rate is analyzed.Simulation results show that wavelet de-noising can get better gain in SNR than traditional digital filter.
