Orthogonal Frequency Division Multiplexing (OFDM) is a powerful technique employed in com- munications systems suering from frequency selectivity. Combined with multiple antennas at the transmitter and receiver as well as adaptive modulation, OFDM
This book describes the Direct3D graphics pipeline, from presentation of scene data to pixels appearing on the screen. The book is organized sequentially following the data °ow through the pipeline from the application to the image displayed on the
The use of multiple antennas at both ends of a wireless link (MIMO technology) holds the potential to drastically improve the spectral eciency and link reliability in future wireless communications systems. A particularly promising candidate for ne

Abstract—In this paper, we analyze spatial multiplexing tech- ques for the downlink of a multiple-input–multiple-output MIMO) orthogonal frequency-divisionmultiplexing (OFDM) sys- m. Our study is focused on outdoor environments characterized y a mod
The number of mobile subscribers has increased tremendously in recent years. Voice communication has become mobile in a massive way and the mobile is the preferred way for voice communication. At the same time the data usage has grown fast in those
The use of multiple antennas at both ends of a wireless link (MIMO technology) holds the potential to drastically improve the pectral eciency and link reliability in future wireless communications systems. A particularly promising candidate for nex
Now is an exciting time for mobile developers. Mobile phones have never been more popular, and powerful smartphones are now a popular choice for consumers. Stylish and versatile phones packing hardware features like GPS, accelerometers, and touch sc

In this paper, we present a multi-scale dictionary learning paradigm for sparse and redundant signal representa- tions. The appeal of such a dictionary is obvious—in many cases data naturally comes at different scales. A multi-scale dictionary shoul
