Synchronization procedure symbol timing in communications systems.

摘要

A method for adjusting symbol timing in a first communications device in Orthogonal Multiplexer system frequency division (OFDM), the method comprising: - determining a timing adjustment receiver symbol is made in order to adjust the receiver symbol timing in said first communications device to synchronize receiver symbol timing to the symbol timing of a second communications device; characterized by - adjusting the symbol timing of a transmitter in said first communications device as a function of said determined timing adjustment receiver symbol; and - said step of adjusting symbol timing of the transmitter including selecting one of a first and a last symbol in a dwell to be modified to adjust the symbol timing of the transmitter, said span a period of time during which said transmitter It maintains the same tone, or a period of time comprising multiple symbol times prior to switching to another tone or set of tones.
