Metasurfaces have drawn significant attentions due to their superior capability in tailoring
electromagnetic waves with a wide frequency range, from microwave to visible light …

In this paper, we propose an algorithm for suppressing intercarrier interference due to phase
noise in coded orthogonal frequency division multiplexing (OFDM) systems. The algorithm …

Ranging from the theoretical basis of UWB sensors via implementation issues to
applications, this much-needed book bridges the gap between designers and appliers …

Communication receivers that utilize I/Q downconversion are troubled by amplitude and
phase mismatches between the analog I and Q branches. These mismatches are …

Physical layer security is known as a promising paradigm to ensure secure performance for
the future beyond 5G (B5G) networks. In light of this fact, this paper elaborates on a tractable …

Building compact and low-cost yet flexible and reconfigurable radios for future wireless
systems is generally a challenging task. On one hand, the needs for flexibility and re …

The current trend in building low-cost yet flexible radio transceivers is to use the so-called
direct-conversion principle, which is based on complex (I/Q) up-and down conversions …

Abstract The realization of Software Defined Radio (SDR) requires flexible RF front-end to
accommodate multiple standards in different frequency bands. In this review paper, we …

In this paper, we present a novel nonlinear digital self-interference canceller algorithm, its
implementation details on a software-defined radio (SDR) platform, and performance results …

Direct-conversion architectures can offer highly integrated low-cost hardware solutions to
communication transceivers. However, it has been demonstrated that radio frequency (RF) …
