چکیده
This document presents technical descriptions of signal processing and cross-layer algorithm design for beamforming from high altitude platforms (HAPs) to ground terminals, and vice versa, using advanced antenna types so-called 'smart antennas'. The research covers topics including vertical antenna arrays for communications from HAPs, optimised antenna array beampatterns for cellular coverage from HAPs, array topologies and SINR balancing in adaptive beamforming from HAPs, data communications to trains from HAPs incorporating DOA estimation and tracking methods, LMS-based beamforming with Doppler recovery and RLSbased beamforming for single carrier IEEE 802.16, both focussed towards HAP applications, and the development of a DSP simulator for smart antenna terminals. Keyword list: Smart antennas, HAPs, beamforming, array signal processing, DOA estimation antenna types for aerial platform and ground terminals CAP-D17-WP3.3-UOY-PUB-01 31st Jan 06 FP6-IST-2003-506745 CAPANINA Page 2 of 2 DOCUMENT HISTORY Date Revision Comment Author / Editor Affiliation 31 Jan 06 01 First issue George White UOY Document Approval (CEC Deliverables only) Date of approval Revision Role of approver Approver Affiliation 31 Jan 06 01 Editor (Internal reviewer) Marina Mondin POLITO 31 Jan 06 01 On behalf of Scientific Board David Grace UOY Beamforming algorithms and implementation aspects CAP-D17-WP3.3-UoY-PUB-01

Distance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملSum-Rate Maximization Based on Power Constraints for Cooperative AF Relay Networks
In this paper, our objective is maximizing total sum-rate subject to power constraints on total relay transmit power or individual relay powers, for amplify-and-forward single-antenna relay-based wireless communication networks. We derive a closed-form solution for the total power constraint optimization problem and show that the individual relay power constraints optimization problem is a quad...

Reducing the amount and intensity of surface runoff, thus reducing erosion is one of the important aspects of natural resource management, watershed management and soil conservation. Land surface conditions and particularly vegetation is Mitigating or aggravating factor in erosion. Studies on the effect of ground cover to reduce erosion rates indicate that is not necessary to ground cover to re...
متن کاملParallel Implementation of Particle Swarm Optimization Variants Using Graphics Processing Unit Platform
There are different variants of Particle Swarm Optimization (PSO) algorithm such as Adaptive Particle Swarm Optimization (APSO) and Particle Swarm Optimization with an Aging Leader and Challengers (ALC-PSO). These algorithms improve the performance of PSO in terms of finding the best solution and accelerating the convergence speed. However, these algorithms are computationally intensive. The go...
متن کاملAdaptive Antennas in Wireless Communication Networks
Wireless Ad-hoc networks can be considered as a means of linking portable user terminals that meet temporarily in locations where connection to a network infrastructure is difficult. Hence, techniques are needed that contribute to the development of high-performance receiving antennas with the capability of automatically eliminating surrounding interference. Solutions to this problem for the co...
