A low rate of signal element transmissions in a communication system and a low SNR at the receiving side results in a normalized large frequency offset. To address this problem, the paper compares the performance from the aspect of the computational complexity, stability, noise immunity, and estimation accuracy. The performance is evaluated under different carrier frequency synchronization algorithms...
Extremely low frequency (ELF) atmospheric noise is non-Gaussian, consisting of the sum of a Gaussian background and narrow pulses caused by lighting strokes. Therefore, the conventional detection method for signal in Gaussian noise gets worse. In this paper, myriad filter and locally optimal detector for signal detection in the ELF atmospheric noise is derived. First, the ELF atmospheric noise is...
Extremely low frequency (ELF) atmospheric noise is non-Gaussian, consisting of the sum of a Gaussian background and narrow pulses caused by lighting strokes. Therefore, the conventional detection method for signal in Gaussian noise gets worse. In this paper, a new structure for signal detection in the ELF atmospheric noise is proposed. First, the ELF atmospheric noise is modeled as a symmetric α-stable...
Very low-frequency (VLF) atmospheric noise is nonGaussian, consisting of the sum of a Gaussian background and narrow pulses caused by lighting strokes, and conventional denoising method fails on it. In this paper, a new strategy to suppress the VLF atmospheric noise is proposed. First, the corrupt signal is passed through a median filter and the impulses in the atmospheric noise are suppressed. Then...
