The bandwidth and reliability of the reverse link (or uplink) as the performance metrics of real-time traffic are studied in this paper. A two-level full factorial design of experiment (DOE) was conducted to identify the impact on the bandwidth and reliability of four factors: packet size, data streaming rate, time of the day, and buffer size in a real network environment. Two extreme cases for each...
A ubiquitous mixed reality system based on ldquoexperience contentsrdquo is presented. The 3D contents provided for users are associated with Korean ancient military weapons such as the turtle ship and the fire wagon, and overlaid on the real images captured by a UMPC camera while looking at the particular weapon displayed in the science museum. For an exact registration of the virtually modeled objects...
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
This paper studies efficient complex valued matrix manipulations for multi-user STBC-MIMO decoding. A novel method called Alamouti blockwise analytical matrix inversion (ABAMI) is proposed for the inversion of large complex matrices that are based on Alamouti sub-blocks. Another method using a variant of Givens rotation is proposed for fast QR decomposition of this kind of matrices. Our solutions...
