TDD Linjär Precoding Metoder för nästa generations mobila kommunikationssystem (Swedish)
Abstract [en]

The mobile communication has stepped into the era of the third generation (3G) worldwide, and plenty of new products and services for mobile communications are emerging every day, for giving people better audio and video experience. Recently, the fourth generation (4G) is starting to be deployed in some countries. However, people cannot help to wonder what will the next generation mobile communication system look like? In this thesis, we give our prediction about the next mobile communication system, which extends the capacity in spatial domain by using a large number of antennas and still keeps the compatibility with the former generation mobile communication systems. However, for the incompatible part—precoding—in such new system, we present two TDD linear precoding methods in this thesis. Through simulations, we can see that these two precoding methods are feasible for the new system and help to increase its throughput performance.

Abstract [sv]

I denna avhandling ger vi våra förutsägelse om nästa mobila kommunikationssystem, som utökar kapaciteten i rumsliga domän med hjälp av ett stort antal antenner och fortfarande håller förenligheten med den tidigare generationens mobila kommunikationssystem. Men för det oförenliga del-precoding-in sådana nya system, presenterar vi två TDD linjär precoding metoder i denna avhandling. Genom simuleringar kan vi se att dessa två precoding metoder är möjlig för det nya systemet och bidra till att öka dess kapacitet prestanda.
