Sentence examples for by using the pilots from inspiring English sources

In time division duplex (TDD) massive MIMO systems, the BS estimates the uplink channel by using the pilots that users send in the uplink, and then the downlink CSI can be easily acquired by using existing channel reciprocity in TDD systems.

The conventional phase tracking scheme proposed in [17] is also applied to all the data symbols by using the pilot subcarriers.

We have suggested an efficient PU detection scheme for CR systems, which performs the nonquiet channel sensing by using the pilot cancellation technique.

The experimental conditions for the determination of drop size and size distribution in the presence of silica nanoparticles (0.025 and 0.05 wt%) were studied by using the pilot plant Oldshue-Rushton extraction column.

Although this method can achieve lower complexity by assuming the linear changing of CIR within one OFDM symbol period, it has a difficulty to estimate the CFR matrix precisely by using the pilot subcarriers in the frequency domain because the received pilot subcarriers are also affected by the ICI in higher time-varying fading channels [12].

To solve the above problem on the CFR estimation by using the pilot subcarriers for the CP-OFDM and ZP-OFDM signals in higher time-varying fading channels, a PN time domain sequence is employed as the TS in the estimation of CFR as well as the role of GI for the TS-OFDM signal [13].

Representativeness of the USD mimics was assessed in parallel by using the pilot scale feed stream generated at each step of the process sequence.

The beamforming-weight vector is calculated by BF_DSP using the pilots embedded in the permutated data channel.

However, the estimation accuracy of CFR matrix by using the scattered pilot subcarriers would be degraded due to the occurrence of ICI for the received pilot subcarriers in higher time-varying fading channels [12].

The technological efficiency was demonstrated by the results obtained using the pilot test unit on different industrial effluents from several origins.

Roughly 70 percent of tax refunds are issued electronically, he said, and Treasury is still seeking ways to increase that proportion — but not by using the model tried in the pilot program.
