Spatial and Temporal Communiation Theory Based on Adaptive Antenna Array
نویسندگان
چکیده
This chapter presents a novel theoretical framework for relating the small-scale fading characteristics of a wireless channel to multipath angle-of-arrival. A method is presented for reducing a multipath channel with arbitrary spatial complexity to three shape factors that have simple, intuitive geometrical interpretations. Furthermore, these shape factors are shown to describe the statistics of received signal fluctuations in a fading multipath channel. Examples demonstrate how the shape factors may be applied to real-life problems in channel measurement, level-crossing rate and average fade duration calculations, and coherence distance estimation.

This paper proposes a new spatio-temporal equalization method using a cascade configuration of an adaptive antenna array and a DFE (Decision Feedback Equalizer). The spatio-temporal equalizer with the cascade configuration can be realized in low computational complexity, however, the error performance surface becomes a fourth-order function of the weights, and possibly has two minima. In order ...

In this paper, new method for reduction of Specific Absorption Rate (SAR) in mobile handset is presented. The idea is based on the array antenna theory and this caused that by improvement of the gain, SNR be preserved and instead of one antenna and one strong hotspot, have the two antenna with two weak hotspot. For this array, the antenna must be equal with similar pattern to have the best arra...
