Extreme crowding of electromagnetic spectrum in recent years has led to the emergence of complex challenges in designing sensing and communications systems. Both systems need wide bandwidth to provide a designated quality-of-service thus resulting in competing interests in exploiting the spectrum. Efficient spectrum utilization has led to the emerg...

Integrated sensing and communication (ISAC) has been envisioned as a solution to realize the sensing capability required for emerging applications in wireless networks. For a mono-static ISAC transceiver, as signal transmission durations are typically much longer than the radar echo round-trip times, the radar returns are drowned by the strong resi...

Massive multiple-input multiple-output (M-MIMO) architecture is the workhorse of modern communication systems. Currently, two fundamental bottlenecks, namely, power consumption and receiver saturation, limit the full potential achievement of this technology. These bottlenecks are intricately linked with the analog-to-digital converter (ADC) used in...

Integrated sensing and communication (ISAC) has been envisioned as a solution to realize the sensing capability required for emerging applications in wireless networks, while efficiently utilizing the available spectral, hardware and energy resources. A commonly studied scenario in the ISAC literature involves a transceiver (e.g., a base station) s...

Orthogonal frequency division multiplexing (OFDM) has been adopted in many wireless communication systems. Although OFDM is robust against frequency selective fading, its spectrum is widely spread and thus it causes high out-of-band emission (OOBE). To cope with such a problem, this report focuses on windowed-OFDM (w-OFDM), which multiplies multica...
