We consider the problem of monostatic radar sensing with orthogonal frequency-division
multiplexing (OFDM) joint radar-communications (JRC) systems in the presence of phase …

Mobile devices perform cell search for initial access in cellular-based industrial Internet of
Things (IoT) systems. Existing fifth-generation (5G) new radio (NR) cell-search scheme …

Massive multiple-input multiple-out (MIMO) technology is vital in millimeter-wave (mmWave)
bands to obtain large array gains. However, there are practical challenges, such as high …

Inter-carrier interference (ICI) due to time-variations of the channel and phase noise is a
critical issue in current orthogonal frequency division multiplexing (OFDM) systems. For the …

In OFDM transmission system, phase noise (PN) caused by non-ideal oscillator induces
inter carrier interference (ICI), which is problematic for operation of high order modulation …

Localization is envisioned as a key enabler to satisfy the requirements of communications
and context-aware services in the fifth/sixth generation (5G/6G) communication systems …

Phase noise is one of the major impairments that degrade the performance of orthogonal
frequency division multiplexing (OFDM) systems. When an OFDM system works at high …

Location information is expected to be the key to meeting the needs of communication and
context-aware services in 6G systems. User localization is achieved based on delay and/or …

This paper presents LuMaMi28, a real-time 28 GHz massive multiple-input multiple-output
(MIMO) testbed. In this testbed, the base station has 16 transceiver chains with a fully-digital …

This paper exploits two intrinsic hardware-specific fingerprints in terms of carrier frequency
offset (CFO) and phase noise (PHN) to propose a two-dimensional physical layer …
