Real-time Smart Antenna Processing for Gsm1800 Base Station

We successfully implemented a smart antenna array processor for a GSM1800 base station. The entire array processing run{time is only 1ms, allowing real{time adaptation of the antenna pattern every GSM frame. The array processing is based on the estimation of the DOAs in the uplink. Separate DOA trackers for uplink and downlink, angular selection diversity, and beamforming with broad nulls guara...

Algebraic 3 × 3 , 4 × 4 and 6 × 6 Space - Time Codes with non - vanishing Determinants

In this paper we present algebraic constructions of 3×3, 4× 4 and 6 × 6 Space-Time Codes, achieving full rate and full diversity. These codes have non-vanishing (in fact fixed) minimum determinants when the rate goes to infinity. Their construction is based on cyclic algebras with center equal to an algebraic field based on cyclotomic fields .

Knowledge Base Intelligent Query Processing

In the field of Artificial Intelligence (AI) there exists a long-standing goal for an expert system. Intelligent Query Processing is concerned with in the context of automatically processing NL text query with several Knowledge Base (KB) technique of AI-literature to develop an expert system. An intelligent system requires understanding of related terms like wisdom, knowledge, reasoning, though...
