| 摘要 |
The invention relates to a method for estimating a transmission channel in a receiver of an OFDMA signal formed by a plurality of carriers being modulated by data elements and distributed in the time-frequency domain in the form of successive symbols, said plurality of carriers including pilot carriers, modulated by reference data elements known by receivers, According to the invention, said method comprises:
- a step of receiving a signal comprising a series of n symbols covering at least one resource block;
- a step of making an initial channel estimation by determining said pilot carriers included in said series of symbols;
- a step of determining diagonal entries of a matrix G p for estimating said channel for at least some symbol p among said n symbols;
- a step of determining, in the frequency domain, at least some of non diagonal entries for each matrix G from said interpolated diagonal entries of a subset of matrices G p among the n matrices G corresponding to each symbol. |
