In [37], overlapped pilots are proposed for channel estimation where different transmitters use the same pilot subcarriers, avoiding the decrease in efficiency with an increasing number of transmitters.
Consequently, users who use the same pilot sequence have parallel estimated channels at each BS, while only the amplitudes of their estimates are different (due to the factor (sqrt {p_{lk}} d_{j}(mathbf {z}_{lk})) in (3)).
i lm =i jk =i 0. In this case, user k in cell j use the same pilot sequence as user m in cell j, and there will be coherence pilot contaminated interference.

Using the same pilot plant, DCS and scientific computing environment in different courses lowers the costs, allows the reutilization of results and enables an efficient lab organization.
A beamforming scheme based on the channel estimates obtained from contaminated pilots results in interferences directed to those transmitters using the same pilot [48].
We used the same pilot pattern at the BS and RN and since they were double antenna arrays we allocated different set of pilot subcarriers to perform the estimation.
Using the same pilot testing, double review and categorisation process, two coders will review the full texts of selected articles.
As a result, all cells use the same set of pilots, potentially causing interference from neighboring cells.
The method is applicable to any OFDM/A systems that implements beamforming using dedicated pilots which use the same beamforming antenna weights for both pilots and data.
She said management wanted the attendants to use the same formula as the pilots, but she insisted that the formula should be adjusted for the attendants because they do very different work.
Both locations use the same frequency to talk to pilots, he said, so the Newark disruption affected Westbury.
