A Low Complexity Massive MIMO Detection Scheme Using Angular-Domain Processing

Signal processing complexity and required memory become problematic in massive MIMO systems as the dimension of channel state information (CSI) matrix grows significantly with the large number of antennas and users. To address these challenges, we propose the first angular-domain massive MIMO detection scheme, which is based on three concepts: transferring the baseband processing from the spatial

Mätningar och experiment på laborationsprocesser

Detta examensarbete behandlar fyra helt skilda processer: Plask och Pysen, elektriskt servo, varmluftsaggregat samt vattenuppvärmning, vilka skall ligga till grund for en ny laboration i den allmänna kursen i reglerteknik. För provesserna har, vid behov, en matematisk modell framtagits, vilken sedan i görligaste mån experimentellt bekräftats. I ett till varje process hörande appendix ges förslag t

Bestämning av parametrar i dynamisk modell för insulinsvar på glykoslast

Quantification of parameters of a simple dynamic glucose-insulin model was performed. Measured data from seven test subjects were used. The Model was simulated by SIMNON and optimized by OPTA. The results are presented and their validity are discussed. Some problems when using OPTA are given account for.

Generella beräkningar på mätdata

This report describes an interactive program which performs computations on data files. The basic idea is that the user describes the computations by writing statements (similar to SIMNON statements) in a file. These statements are compiled and a pseudo code is created. By interpreting this code the program can perform the computations. The program is run by entering commands from a teletype. The
