RESEARCH OVERVIEW

Abstract

The orthogonal frequency multiplexing, defined by the abbreviation OFDM, provides a
significant increase in the bandwidth of the radio channel due to the improvement in spectral
efficiency. In addition, the use of OFDM allows the transmission speed to be increased
without increasing the frequency range or modulation level. Therefore, OFDM is used in
modern wireless systems, such as IEEE 802.11 (Wi-Fi) and IEEE 802.16 (WiMAX), as well
as in wired ADSL.
