Sentence examples for estimate channel from inspiring English sources

Conventional schemes [2-4] detect superposed band and estimate desired to undesired signal power ratio (DUR), where they do not estimate channel estimation error so that the LLR is set without taking channel estimation error into account.

A channel estimation technique that can simultaneously estimate channel frequency response and timing misalignment in generalized frequency division multiple access is described.

Although the main purpose of inserting pilot OFDM symbols is to estimate channel coefficients, in addition to channel estimation, we exploit them to estimate noise and interference power based on the technique proposed in [18].

In addition, an approach using the EM algorithm is applied to address the frequency estimation problem in OFDM spectrum sharing systems [13] and to estimate channel coefficients [14].

In the scheme, it is necessary to insert more pilot signals for initial estimation of the interference power than those just required to estimate channel coefficients, which are large overhead for systems.

Superimposed training (ST) is used to estimate channel in orthogonal frequency division multiplexing (OFDM) systems which results in higher throughput than the time/frequency multiplexed training schemes.

CS-based approaches try to estimate channels individually while DCS-based channel estimation tries to estimate jointly sparse channels altogether.

CS-based approaches try to estimate channels individually while DCS-based channel estimation tries to determine jointly sparse channels altogether.

Pilot symbols are inserted to estimate channels and IFFT is taken at each transmitter antenna.

The relay transmits an orthogonal sequence to estimate channels at the end of the BC time slot.

Base stations estimate channels usually based on least squares (LS) [3] or minimum mean square error (MMSE) [7 9] methods.
