Reciprocity calibration methods for Massive MIMO based on antenna coupling

In this paper we consider time-division-duplex (TDD) reciprocity calibration of a massive MIMO system. The calibration of a massive MIMO system can be done entirely at the base station (BS) side by sounding the BS antennas one-by-one while receiving with the other BS antennas. With an M antenna BS, this generates M(M - 1) signals that can be used for calibration purposes. In this paper we study se

Human IgE - What We Can Learn from Repertoire Studies and How We Can Use Them as Tools

Popular Abstract in Swedish Människans immunförsvar har utvecklats under miljontals år för att i bästa möjliga mån skydda oss från infektioner och det sköter i de allra flesta fall det jobbet utmärkt. Ibland händer det dock att någonting går fel och konsekvensen kan bli väldigt obehaglig eller till och med förödande för den drabbade. Allergiska reaktioner är ett utmärkt exempel på en sådan situatiAntibodies of the IgE isotype play a key role as the allergen recognizer in allergic disease, which today affects as much as a third of the population in the industrialized parts of the world. Despite this crucial role of IgE, our knowledge of IgE repertoires and how we can utilize the information hidden in monoclonal IgE to improve the quality of life of allergic patients, is limited.

Eye movements play an active role when visuospatial information is recalled from memory

Abstract in Undetermined Whilst it has been established that spontaneous eye movements occur with visual imagery and that they are comparable with those from an original scene inspection (e.g., Brandt & Stark, 1997; Johansson, Holsanova, & Holmqvist, 2006), the exact purpose of these eye movements has been a hot topic of debate (cf., Ferreira et al., 2008; Richardson et al., 2009). Do they

Physical bounds on antennas of arbitrary shape

Recently developed physical bounds relate antenna performance to the polarizability of the antenna structure. Although, the polarizability can be determined numerically for arbitrary objects, it is advantageous to have simple closed form expressions for canonical geometries. Here, rational approximations are presented for the polarizability of cylinders and planar rectangles.

High temperature waveguide measurements of the permittivity and permeability

This paper describes a setup for measurements of the permittivity and the permeability at temperatures from room temperature up to 1000 °C using a single rectangular waveguide. The hardware design of the setup that can handle these temperatures is developed and described. Measurements on a NiZn ferrite sample are performed in order to evaluate the performance of the setup and the procedure that is
