Sentence examples for matrices in frequency from inspiring English sources

Boldface uppercase letters are used for both vectors and matrices in frequency domain.

Discrete Fourier transform enables us to propose a new algorithm based on uniform sampling of polynomial matrices in frequency domain.

The raw data for this goal are the added mass and potential-damping matrices in frequency-discrete domain.

The corresponding diagonal matrix in frequency domain results from (3) based on, that is, (14).

The channel autocorrelation matrix in frequency domain can be expressed as. (7).

Similarly, it needs to know the channel autocorrelation matrix in frequency domain, the Doppler shift, and SNR in advance.

In [14], the linear minimum mean square error (LMMSE) channel estimation method based on channel autocorrelation matrix in frequency domain has been proposed.

The drawback of LMMSE channel estimation [6, 14] is that it requires the knowledge of channel autocorrelation matrix in frequency domain and the signal to noise ratio (SNR).

Since the conventional LMMSE channel estimation requires the channel statistics, that is, the channel autocorrelation matrix in frequency domain and SNR, which are often unavailable in practical systems, the application of the conventional LMMSE channel estimation is limited.
