INTERPOLATION DE PUISSANCE DE BRUIT DANS UN SYSTEME MULTI-PORTEUSES

摘要

#CMT# #/CMT# The method involves determining M estimated noise power values at frame level. Each estimated noise power value is related to one of M emitted reference symbol blocks of a frame. The reference symbols in each of the blocks satisfy a maximum spacing between each other along a time axis and another maximum spacing between each other along a frequency axis, less than two values respectively. Values of the estimated noise power for the other symbols in the frame are then obtained from the determined estimated noise power values. #CMT# : #/CMT# Independent claims are also included for the following: (1) a reception device for implementing a method of receiving a signal in a telecommunication network; and (2) a telecommunication system comprising a transmission device and a reception device. #CMT#USE : #/CMT# Used in a reception system such as an orthogonal frequency division multiplexing (OFDM) signal reception system, an orthogonal frequency division multiplexing/isotropic orthogonal transform algorithm (OFDM/IOTA) signal reception system or an orthogonal frequency division multiplexing/offset quadrature amplitude modulation (OQAM) signal reception system for receiving a multi-carrier radio signal in a telecommunication network (claimed) in the form of signals received on corresponding antennas. #CMT#ADVANTAGE : #/CMT# The method allows estimation of the likelihood of the transmitted information that is based on an estimation noise power from the received signal in a precise and correct manner, thus improving the performance of the reception system. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows main steps of a multi-carrier radio signal receiving method. `(Drawing contains non-English language text)`.
