Abstract:
1. A signal reception method in a telecommunication network comprising reception of a number P of signals on P corresponding antennas, where P is an integer greater than or equal to 1; wherein the received signals correspond to a multi-carrier signal transmitted in the form of successive frames comprising symbols occupying corresponding positions distributed along a time axis and along a frequency axis; wherein one frame comprising M blocks each with at least N reference symbols, the reference symbols in each of the blocks satisfying a first maximum spacing between each other along the time axis and a second maximum spacing between each other along the frequency axis, less than a first value and a second value respectively, and M being an integer number equal to at least two, the process being based on an estimate of the noise power, including the following steps: /a/ determine M estimated noise power values at frame level, each related to one of the M emitted reference symbol blocks; /b/ obtain values of the estimated noise power relative to other symbols in the frame by interpoling said M estimated noise power values.
