Due to their ability to provide high data rates for multimedia applications, multi-carrier modulation techniques have gained a strong interest for wide area, local area, and personal area networks over the last decade. A special case of multi-carrier modulation is orthogonal frequency division multiplexing (OFDM) that can overcome many problems that arise with high bit rate communication, the biggest of which is the time dispersion. OFDM has found applications in many wireless technologies including digital audio and video broadcasting in Europe, high-speed wireless local area networks (WLANs) standards in Europe (Hyperlan2) and USA (IEEE 802.11a/g/n). Recently, it has been applied to wireless metropolitan area networks (WMANs) for fixed and mobile wireless access (e.g. 802.16- 2004 for fixed and 802.16-2005 for mobile WiMAX), fourth generation cellular wireless with Long Term Evolution (LTE) and LTE-Advanced, wireless personal area networks (WPANs) through multiband Ultra WideBand, and wireless regional area networks (WRANs) through cognitive radio (IEEE 802.22). Nowadays, during the development of 5G, flexible OFDM concepts are being discussed along with other possible waveforms. Beyond 5G technologies (like 6G) will require major upgrades for waveform to accommodate wide variety of services with various user and channel conditions. Therefore, understanding waveforms (especially OFDM-and-beyond) and the related technologies is very important for those students who seek for a career in the communications field, especially in wireless communications. This course will cover the details of various waveforms including OFDM and OFDM based technologies.
