—This paper consider cooperative localization in cellular networks. In this scenario, several located mobile terminals (MTs) are employed as reference nodes to find the location of an un-located MT. The located MTs sent training sequences in the uplink, then the un-located MT perform distance estimation using received signal strength techniques. The(More)
The switched reluctance motor (SRM) has obtained great potential as an adjustable speed application due to its outstanding merits. However, its application is limited because of the rotor position sensors and torque ripple. This paper proposes an approach to tackle sensorless control and torque ripple minimization of SRM by using flexible neural networks(More)
—Previous work about cooperative localization in cellular networks usually consider a centralized processor (CP) is available for location estimation. This paper consider cooperative localization in a distributed base station (BS) scenario, where there is no CP, and the distributed BSs are responsible for location estimation. help to find the locations of(More)
One of the major challenges of Cellular network based localization techniques is lack of hearability between mobile terminals (MTs) and base stations (BSs), thus the number of available anchors is limited. In order to solve the hearability problem, previous work assume some of the MTs have their location information via Global Positioning System (GPS).(More)
Switched reluctance motor (SRM), which has simple construction, high reliability, high efficiency and low cost, has shown its strong competition in many fields. However, mechanical position sensors add to the cost, complexity and potential unreliability at high speed. This paper presents an approach of rotor position estimation for switched reluctance motor(More)
Current wireless communication market has a demand for high performance and low cost 33deg base station antenna. In this paper the design topology of a low cost 33deg base station antenna is presented. The frequency band is 1710-2170 MHz. The single antenna element used in the antenna array is an aperture-coupled cross polarized patch antenna. The antenna(More)
