Adaptive Antenna Impedance Matching Using Low-Complexity Shallow Learning Model
Hasan, Mohammad Mahmudul; Cheffena Gebresilassie, Michael (Peer reviewed; Journal article, 2023)In this paper, an automatic antenna impedance matching technique is presented for a wide range of frequency bands where a low-complexity shallow learning model adaptively determines the component values of the matching ... -
Data Aided Channel Estimation for MIMO-OFDM Wireless Systems Using Reliable Carriers
Khan, Inaamullah; Cheffena Gebresilassie, Michael; Hasan, Mohammad Mahmudul (Peer reviewed; Journal article, 2023)Wireless channel estimation is one of the challenging problems in multiple input multiple output orthogonal frequency division multiplexing (MIMO-OFDM) wireless systems. The MIMO-OFDM exploits the spatial resources and ... -
