CHANNEL ESTIMATION BY METRIC SELECTION BETWEEN A 2-D AND A 1-D BASED FREQUENCY CHANNEL ESTIMATION |
摘要 |
<p>Channel estimation for a wireless Orthogonal Frequency Division Multiplexed (OFDM) link having pilots on at least some carriers in at least some symbols may be implemented by performing first and second channel estimation processes. The first channel estimation process uses only frequency domain interpolation of the pilots to obtain a first candidate channel estimate for the OFDM link, and the second channel estimation process uses both time domain interpolation and frequency domain interpolation of the pilots to obtain a second candidate channel estimate for the OFDM link. One of the first and second candidate channel estimates is selected for processing a communication received via the OFDM link.</p> |
