Sentence examples for frequency domain echo from inspiring English sources

(b) Frequency domain echo before synchronization.

(d) Frequency domain echo after synchronization.

Specifically, in the unified frequency domain architecture, the acoustic echo and noise signal are efficiently able to be suppressed through the acoustic echo suppression algorithm based on soft decision without the help of the additional noise reduction technique.

Furthermore, the overall spectrum of the echo is shifted upward due to the bat's own flight speed, separating pulse and echo in the frequency domain.

Until now, we get the general echo model in frequency domain.

We use the partial differential Maxwell's equations to derive the electronic field and then obtain the general echo model in frequency domain and time domain.

In [6], Gustaffson et al. used a single perceptually motivated weighted rule to suppress both noise and residual echo in a frequency domain.

In Section 3, a new CS matrix is constructed for the CS imaging based on the above general echo model in frequency domain.

In this paper, to avoid error as much as possible, we try to find a CS matrix for the general echo model in frequency domain directly.

Because we use the general echo model in frequency domain, the CS matrix Ψ is also the function of the general transmitted signal in frequency domain P(ω m ).

After analyzing the relationship between the general echo model in frequency domain and the existing model in time domain, a compressive sensing (CS) matrix is constructed from random partial Fourier matrices for processing the range CS SAR imaging.
