PULSE SHAPING FOR MULTICARRIER MODULATION

摘要

A method and system for data transmissionin an orthogonal frequency division multiplexed(OFDM) system is provided. In the inventioneach of a plurality of data symbols C k, having asymbol period T, are modulated (404) onto one ofa plurality of subcarriers comprising a first datasignal. The first data signal is then multiplied(406) by a pulse-shaping function over the periodT to generate a second data signal. The seconddata signal is then modulated (412) and transmit-tedon a system carrier over a communicationschannel (414) of the OFDM system.
