<p>A process for estimating the channel in a OFDM communication system, said OFDM sample being based on a time-frequency grid comprising a set of pilots.
- receiving a OFDM sample based subframes comprising a set of pilots signals;
- performing an iterative loop for the purpose of computing (M k , k k ) respectively corresponding to the variance and the mean of the probability distribution of p ( h k | y k , I k ) at time instant k, y k , and I k respectively corresponding to the received signal and to a priori known information;
said value of (M k , k k ) being computed as a function of (M k-1 , k k-1 ), » being the time correlation between channel estimate h k and h k-1 , as well as the values of the pilots received at instant k. The invention is particularly adapted for a LTE receiver.</p> |
