Enhanced Time-Frequency Representation and Mode Decomposition
Haijian Zhang, Guang Hua
Time-frequency representation (TFR) allowing for mode reconstruction plays a significant role in interpreting and analyzing the nonstationary signal constituted of various modes. H…
Subcarrier-wise Backscatter Communications over Ambient OFDM for Low Power IoT
Mahyar Nemati, Morteza Soltani, Jie Ding +1
Ambient backscatter communication (AmBC) over orthogonal-frequency-division-multiplexing (OFDM) signals has recently been proposed as an appealing technique for low power Internet-…
Choosing a sampling frequency for ECG QRS detection using convolutional networks
Ahsan Habib, Chandan Karmakar, John Yearwood
Automated QRS detection methods depend on the ECG data which is sampled at a certain frequency, irrespective of filter-based traditional methods or convolutional network (CNN) base…
RIS-Assisted Coverage Enhancement in Millimeter-Wave Cellular Networks
Mahyar Nemati, Jihong Park, Jinho Choi
The use of millimeter-wave (mmWave) bandwidth is one key enabler to achieve the high data rates in the fifth-generation (5G) cellular systems. However, mmWave signals suffer from s…
Machine learning and data analytics for the IoT
Erwin Adi, Adnan Anwar, Zubair Baig +1
The Internet of Things (IoT) applications have grown in exorbitant numbers, generating a large amount of data required for intelligent data processing. However, the varying IoT inf…
Short-Range Ambient Backscatter Communication Using Reconfigurable Intelligent Surfaces
Mahyar Nemati, Jie Ding, Jinho Choi
Ambient backscatter communication (AmBC) has been introduced to address communication and power efficiency issues for short-range and low-power Internet-of-Things (IoT) application…
