METHOD AND APPARATUS FOR RECEIVING NUMERICAL SIGNALS TRANSMITTED BY CODED FREQUENCY DIVISION MULTIPLEXING FOR TRANSMISSION SYSTEMS, IN PARTICULAR OF THE SPATIAL DIVERSITY TYPE

摘要

The invention relates to a method for receiving coded frequency division multiplexing numerical signals, said method comprising the steps of: - receiving, through a receiver, at least one coded frequency division multiplexing numerical signal, said at least one signal comprising a plurality of symbols coded according to a numerical modulation and transmitted at time instants which are normalized with respect to the duration of a symbol; - estimating a transfer function of at least one transmission channel through which said at least one numerical signal is received. The invention is characterized in that, in order to demodulate said at least one signal received at a certain time instant, said method uses said transfer function estimated at the previous time instant.
