In this seminar we are inviting Prof Arafat Al-Dweik from Khalifa University to deliver a talk titled as "Data Detection for SISO and MIMO Communications Systems".

Abstract

Orthogonal frequency division multiplexing (OFDM) is widely adopted in several wired and wireless communication standards including the fourth-generation (4G) wireless networks, Digital Video Broadcasting (DVB), Terrestrial (DVB-T) and Hand-held (DVB-H), optical wireless communications (OWC), and recently, it has been adopted for the fifth generation (5G) New Radio (NR). OFDM has been also adopted for power-line communications (PLC), satellite communications, and the narrow-band Internet of Things (NBIoT). The key to OFDM popularity is that each subcarrier experiences flat fading even though the overall signal spectrum suffers from frequency-selective fading. Moreover, appending the cyclic prefix (CP) prevents inter-symbol interference (ISI), and hence, a low-complexity single-tap equalizer can be utilized to eliminate the impact of the multipath fading channel. Under such circumstances, the OFDM demodulation process can be performed once the fading parameters at each subcarrier, commonly denoted as channel state information (CSI), are estimated. Therefore, OFDM is suitable for frequency-selective channels that are experienced in 4G and 5G wireless systems, and flat fading channels which are commonly experienced in OWC under the effect of atmospheric turbulence. However, accurate CSI should be available at the receiver to enable recovering the data symbols reliably. This talk discusses the main principles of OFDM and presents state-of-the-art receiver design, particularly the Direct Data Detection receiver developed by Al-Dweik et al., which does not require channel estimation or equalization to perform coherent data detection. Instead, channel estimation, equalization, and data detection are combined into a single operation.
