Random Access Protocol for Massive MIMO: Strongest-User Collision Resolution (SUCR)
Emil Björnson, Elisabeth de Carvalho, Erik G. Larsson +1
Wireless networks with many antennas at the base stations and multiplexing of many users, known as Massive MIMO systems, are key to handle the rapid growth of data traffic. As the…
Random Access for Massive MIMO Systems with Intra-Cell Pilot Contamination
Elisabeth de Carvalho, Emil Bjornson, Erik G. Larsson +1
Massive MIMO systems, where the base stations are equipped with hundreds of antenna elements, are an attractive way to attain unprecedented spectral efficiency in future wireless n…
Towards Very Large Aperture Massive MIMO: a measurement based study
Àlex Oliveras Martínez, Elisabeth De Carvalho, Jesper Ødum Nielsen
Massive MIMO is a new technique for wireless communications that claims to offer very high system throughput and energy efficiency in multi-user scenarios. The cost is to add a ver…
CoMPflex: CoMP for In-Band Wireless Full Duplex
Henning Thomsen, Petar Popovski, Elisabeth de Carvalho +3
In this letter we consider emulation of a Full Duplex (FD) cellular base station (BS) by using two spatially separated and coordinated half duplex (HD) BSs. The proposed system is…
