MB-OFDM TRANSMITTER AND RECEIVER AND SIGNAL PROCESSING METHOD THEREOF

摘要

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.
