Abstract

A method of improving frequency diversity of a signal that includes a plurality of orthogonal frequency division multiplexing (OFDM) symbols comprises receiving an input data sequence, mapping the input data sequence to a transmission data sequence, wherein the mapping includes performing a mapping operation and generating an OFDM symbol using the transmission data sequence. An orthogonal frequency division multiplexing (OFDM) transmitter comprises an interface configured to receive an input data sequence, and a processor configured to perform a mapping operation, to map the input data sequence to a transmission data sequence wherein the mapping includes performing the mapping operation, and to generate an OFDM symbol using the transmission data sequence.

Description

technical field [0001] The present invention relates to a communication system, more specifically, to an OFDM (Orthogonal Frequency Division Multiplexing) sending device and method thereof. Background technique [0002] MB-OFDM (Multiband Orthogonal Frequency Division Multiplexing) is especially used in wireless communication systems such as UWB (Ultra Wideband) systems. Usually MB-OFDM is used in combination with frequency hopping technology. [0003] MB-OFDM is suitable for devices designed to satisfy Federal Communications Commission (FCC) regulations for UWB devices. According to current regulations, UWB devices are allowed to operate within the frequency bandwidth of 3.1-10.6GHz, and the emission of power is always kept below -41.3dBm / MHz within the signal bandwidth. [0004] In a specific MB-OFDM system, coded bits are sent in the form of OFDM symbols, and each OFDM symbol includes QPSK (Quadrature Phase Shift Keying) or DCM (Dual Carrier Modulation, or tone (tone)) ...
