“…It has been experimentally verified that the maximum transmission/reception can further be improved by adjusting the weighting functions of the array elements [5,6] of smart antenna [7,8]. The concepts of smart antenna are discussed in details in [9,10].…”

Ultra wide band (UWB) impulse radio (IR) technology has different applications in different sectors such as short range radios and collision avoidance radar. A strong signal denoising method is needed for UWB-IR signal detection. One of the challenges of UWB-IR signal detection technique is the environmental interferences and noises. Wavelet Packet Transform (WPT) based multi-resolution analysis technique is suitable for this kind of signal denoising and detection. The paper describes a better method of denoising and detection technique of UWB-IR signal based on calculation of energies of the coefficients of each WPT terminal-node and by using an improved threshold calculation technique. The proposed technique is investigated through both simulation and experimentation.

“…Nevertheless, owing to the continuous amplitude distribution, many different amplifiers would be required for every distinct element, which results in a complex transmitting array. To reduce the kinds of amplifiers, Baki et al and Li et al [7,8] proposed the isosceles trapezoidal distribution (ITD) and stepped-amplitude arrays (SAAs), respectively. The design and implementation of transmitting array could be greatly simplified if all elements are uniformly excited [9].…”

Beam capture efficiency (BCE) is one key factor of the overall efficiency for a microwave power transmission (MPT) system, while sparsification of a large-scale transmitting array has a practical significance. If all elements of the transmitting array are excited uniformly, the fabrication, maintenance, and feed network design would be greatly simplified. This paper describes the synthesis method of the sparse uniform-amplitude transmitting array with concentric ring layout using particle swarm optimization (PSO) algorithm while keeping a higher BCE. Based on this method, uniform exciting strategy, reduced number of elements, and a higher BCE are achieved simultaneously for optimal MPT. The numerical results of the sparse uniform-amplitude concentric ring arrays (SUACRAs) optimized by the proposed method are compared with those of the random-located uniform-amplitude array (RLUAA) and the stepped-amplitude array (SAA), both being reported in the literatures for the maximum BCE. Compared to the RLUAA, the SUACRA saves 32% elements with a 1.1% higher BCE. While compared to the SAA, the SUACRA saves 29.1% elements with a bit higher BCE. The proposed SUACRAs have higher BCEs, simple array arrangement and feed network, and could be used as the transmitting array for a large-scale MPT system.

“…Owing to its "smooth" nature, different amplifiers are needed for each element, thus the feeding network is complex to be realized and maintained. To simplify such a structure, edge tapering [7], [8] and stochastic optimization method [9] have been proposed. However, previous works are mainly concerned with the optimization of array tapering to obtain higher BCE, and CSL is not concerned.…”

This paper describes a synthesis method of uniformly excited unequally spaced planar array with maximum beam collection efficiency (BCE) based on Chaotic Particle Swarm Optimization (CPSO) algorithm. And here the multiple optimization constrains include the number of array elements, the aperture, the minimum element spacing, and the maximum sidelobe level (SLL) outside the receiving region. Through this method, feeding network of the array becomes simple and compact. Effectiveness of the proposed method is validated by comparing the simulation results obtained in this paper to those reported in the state-of-the-art literature.Index Terms-Antenna arrays, microwave power transmission, chaotic particle swarm optimization, solar power satellite.
