CHANNEL ESTIMATION USING AVERAGING AND INTERPOLATION |
| 摘要 |
A method of performing channel estimation includes receiving a frame that includes, for each subcarrier of a subset of subcarriers in the frame, a pair of pilot symbols in the subcarrier. The subcarriers of the subset are regularly spaced apart from one another in the frequency domain. Time-averaged channel estimates for each subcarrier of the subset are generated based on the pairs of pilot symbols. Frequency-averaged channel estimates for respective subcarriers are generated based on the time-averaged channel estimates. Interpolation is performed between respective frequency-averaged channel estimates to generate interpolated channel estimates for subcarriers between the respective subcarriers. |

1. A method of performing channel estimation, comprising:
receiving a frame comprising, for each subcarrier of a subset of subcarriers in the frame, a pair of pilot symbols in the subcarrier, wherein the subcarriers of the subset are regularly spaced apart from one another in the frequency domain; generating time-averaged channel estimates for each subcarrier of the subset based on the pairs of pilot symbols; generating frequency-averaged channel estimates for respective subcarriers based on the time-averaged channel estimates; and interpolating between respective frequency-averaged channel estimates to generate interpolated channel estimates for subcarriers between the respective subcarriers. |
