This paper presents a reduced-complexity, fixed-point algorithm and efficient real-time VLSI architectures for multiuser channel estimation, one of the core baseband processing operations in wireless base-station receivers for CDMA. Future wireless base-station receivers will need to use sophisticated algorithms to support extremely high data rates and multimedia. Current DSP implementations of...
We consider a periodic-review inventory system with one warehouse and N non-identical retailers. Each location replenishes inventory according to a base-stock policy in a fixed time interval. A fixed cost is incurred for each inventory reorder. The warehouse fills the retailers’ orders in the same sequence as the original demand. The objective is to minimize the long-run average system cost per...
We consider a periodic-review inventory system in which multiple non-identical retailers replenish from a warehouse, which further replenishes from an outside ample source. Each facility faces Poisson customer demand and replenishes according to a base-stock policy in a fixed time interval. There are fixed costs incurred for placing an order. The warehouse fills the retailers’ orders in the sam...
This paper proposes an indicator of seismic performance based on life-cycle cost of a building. It is expressed as a ratio of lifetime damage loss to life-cycle cost and determines the seismic performance of isolated buildings. Major factors are considered, including uncertainty in hazard demand and structural capacity, initial costs, and expected loss during earthquakes. Thus, a high indicator...
This study explored the seismic response of a house supporting base sides with polymeric displacement control material and by magnetically levitating foundation base. In this paper, we explore possibility efficacy seismic-isolated detached as described above from both shaking table experiment model three-dimensional finite element analysis. The showed stable its acceleration was significantly r...
Abstract— Consider a wireless system with multiple and independent user-base pairings over some region. Each user tries to greedily optimize its performance, and eventually a simultaneous water-filling fixed point is reached. Here we seek to analytically understand properties of different water-filling fixed points. In so doing we show that water-filling alone does not generally result in optim...
In the context of constructive locale or frame theory (locale theory over a fixed base locale), we study some aspects of ’frame distributions’, meaning sup preserving maps from a frame to the base frame. We derive a relationship between results of Jibladze-Johnstone and Bunge-Funk, and also descriptions in distribution terms, as well as in double negation terms, of the ’interior of closure’ ope...
The design of a wireless local area network (WLAN) has two major issues: determining the best placement of base stations (BS) and assigning the frequency channels for those stations. The correct BS placement minimizes installation costs. The adequate channel assignment reduces signal interference and improve network throughput. This paper reports a real experience where we applied the concepts ...
We present two methods for lossy compression of normal vectors through quantization using “base” polyhedra. The first revisits subdivision-based quantization. The second uses fixed-precision barycentric coordinates. For both, we provide fast (de)compression algorithms and a rigorous upper bound on compression error. We discuss the effects of base polyhedra on the error bound and suggest polyhed...
