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.
