Device authentication is essential for securing Internet of things. Radio frequency fingerprint
identification (RFFI) is an emerging technique that exploits intrinsic and unique hardware …

A canonical wireless communication system consists of a transmitter and a receiver. The
information bit stream is transmitted after coding, modulation, and pulse sha**. Due to the …

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

Radio frequency fingerprinting (RFF) serves as a distinctive hardware trait in transmitters,
forming the cornerstone of transmitter identification. While recent advancements led to …

This article proposes a novel adaptive architecture for blind identification and compensation
of frequency response mismatches in 4-channel time-interleaved analog-to-digital …

Frequency-dependent I/Q imbalance is one of the major impairments in the direct-
conversion receivers (DCR) for high-speed wideband wireless systems. We propose two …

We propose a novel pilot-aided compensation scheme for carrier frequency offset (CFO) and
I/Q imbalance. The proposed scheme comprises a generalized periodic pilot and a low …

The performance of zero intermediate frequency (IF) receiver is usually limited by the
frequency dependent I/Q mismatch, which gets worse with the increase of the signal …

In this paper, novel blind identification and compensation architectures for the frequency
response mismatch of a two-channel time-interleaved analog-to-digital-converter (TI-ADC) …

The gain/phase imbalances and DC-offsets in the in-phase and quadrature branches in
direct conversion transmitters (DCTs) are main sources of errors, especially at microwave …
