<p>Methods, systems, and apparatuses to estimate a channel with discontinuous instances of a pilot signal. A pilot signal is received during a first and second time period. The time periods are separated by a blank period. The pilot signal is not received during the blank period. A pilot signal received during the second time period is combined with a pilot signal received during the first time period. A channel estimate is based on the combination. According to a second method, pilot signals are received. A first and second channel estimate is calculated based on the pilot signals. Data symbols are received following the pilot signals. A third channel estimate is extrapolated from the channel estimates. This channel estimate corresponds to a virtualized instance of the pilot signal. The data symbols are interpolated based on the second and third channel estimates.</p> |
