INITIALISATION OF OFDM DATA TRANSMISSION AND MODEM FOR OFDM DATA TRANSMISSION Russian patent published in 2010 - IPC H04J11/00

Abstract RU 2408142 C1

FIELD: information technology.

SUBSTANCE: invention relates to orthogonal frequency division multiplex (OFDM) data transmission. The method of initialising OFDM data transmission involves synthesis of an input filter (32) in a modem (3) based on an estimated channel transfer function K₀ of a physical line (21) and selecting the number of readings of a protective interval based on pulsed response of a communication channel (2) containing the physical line (21) and the synthesised input filter (32).

EFFECT: efficient data transmission through orthogonal frequency division multiplex.
