When combined and applied to a synchronizing apparatus such as a Costas loop, the signals provide improved performance at low SNR and avoid the need to know the carrier frequency when setting the delay.doi:US4531224 ARonald D. McCallister
2. The C2 coherency algorithm has good stability, suitable for low signal noise ratio data, but lateral resolution is low. C2相干算法具有较好的稳定性,适于低信噪比数据资料,但横向分辨率低。 paper.pet2008.cn3. Detect effect will be much lower with these methods in low signal noise ratio ...
This simple but novel idea will solve the physical problem to implement lock-in amplifier for low frequency signal DC level detection application in the fields of bio-signal sensing or nano-ampere signal detection application. 展开 关键词: Lock-in amplifier clock synchronization S/N ratio phase ...
After the derivation of an approximate expression of MIMO system capacity at low signal-to-noise ratio levels, a novel method for further increasing MIMO system capacity was proposed. The transmit or receive antennas were selected out at the receiver side according to the Frobenius norm of the ...
Active Signal Processing Enhancements for Classification of Low Signal-to-Noise Ratio (SNR) Sonar Signals in Doppler ClutterTravis Cuprak
Speech separation is a challenging problem at low signal-to-noise ratios (SNRs). Separation can be formulated as a classification problem. In this study, we focus on the SNR level of -5 dB in which speech is generally dominated by background noise. In such a low SNR condition, extracting...

In this paper, an algorithm is developed to estimate the frequencies of the sinusoids corrupted by white noise. First, the input data is analyzed by a large order autoregressive (AR) spectral estimator, and then we root the prediction error filter (PEF) to get a set of zeros. Using a ...
