This paper describes angle-resolved channel measurements at 300 GHz, which were performed in an outdoor environment. An advanced time domain channel sounder and a sounding sequence with a measurement bandwidth of 2 GHz were used in the experiment. Th

Indeed, self-interference cancellation has been proven to be the key-enabling technique for realizing a full-duplex duplexing scheme. However, a self-interference canceller must possess an up-to-date knowledge about its sensed self-interference wirel

In full-duplex wireless communication systems, knowledge about the self-interference channel must be acquired to cancel the self- interference signal. This paper presents results' analysis of indoor measurements of multi-path self-interference wirele

This paper studies the behavior of self-interference radio channels associated with a $4 \times 4$ multiple-input-multiple-output antenna (MIMO) system. Self-interference channel measurements were performed in two indoor environments: Auditorium and

In full-duplex wireless communication systems, transmission signals travel through self-interference radio channels before they will be received by the local receivers. This paper studies time dispersion characteristics of these channels for an indoo

To obtain a better understanding of full-duplex wireless systems, this paper studies the behavior of the self-interference radio channels. It presents a physical model of the self-interference radio channel that splits the channel into two segments

With the expected adoption of millimeter wave technologies for industrial communication, it is fundamentally important to properly understand the radio channel characteristics of such environments. This paper presents the setup, scenario and results

In this letter, we investigate how environment induced shadowing influences a 28.5 GHz access link in an urban open square scenario. Shadowing is caused by cars, buses, lorries, and pedestrians passing between the small cell base station and the mobi

In order to realistically model urban micro-cell environments with low base station heights, a measurement campaign has been conducted in the 3.5–3.8 GHz frequency band. The two scenarios of interest are the Urban Micro (UMi) Campus and Open Square
Robust channel estimation in IEEE 802.11p systems in highly time- and frequency-varying vehicular channels, in combination with long data packets, is a challenging task due to the ill-suited pilot pattern. Solutions of increased receiver complexity t
