The indoor wireless communication in general, suffers from several challenges like, signal reflection, diffraction, and attenuation. With these problems, the error range is increased significantly and the accuracy will be lost. To address those problems, Mini Zone (MZ)e technique propos in this paper which aim to partition building into small areas lead to more simplicity and flexibility to assign suitable parameters for specific area rather than whole building. To do that, case study building separated to seven zone (A-G). Each zone has its specific characteristics related to its contents such as, objects, walls, windows and any types of materials in addition to the distance between transmitters and each zone. We took in account these specific parameters to estimate the correct position. 56 receivers (8 for each zone) and 3 transmitters deployed in the case study building. The Wireless Insite Package has been used to design the chosen building and measure the required parameters. The target position has been estimated depending on RSS and ToA methods The objectives of this study are to implement a dynamic system that has capabilities to estimate position under deference conditions like LOS or NLO with the same accuracy. In addition, study the suitability of TOA and RSS methods to estimate position. These objectives were done based on the proposed technique by decrease error in the whole system to an acceptable level to be (0.293502m). Also, the results confirm that the TOA method was better than RSS by using propos technique.

A Design of MIMO System Based on Y-Shaped with QSCS for UWB Applications

By Nada M. Khalil Al-Ani Oras A. Shareef Al-Ani Mahmood F. Mosleh Read A. Abd-Alhameed

The multi-path fading environment is a major challenge of UWB devices. So, a MIMO system is one of the importance techniques which exploited to mitigate such problems. In this research, a MIMO system with eight ports consists of four antenna elements has proposed. Y-shaped of patch microstrip has chosen to design each element to enhance the bandwidth of the proposed system. In order to achieve a good isolation, the geometry of the ground layer of the proposed antenna element has based on quasi-self-complementary structure. The proposed model has a compact size because it facilitates with dual polarized ports which increase the capacity and maintaining an acceptable size. The results are show that a bandwidth of 2.06 GHz has obtained with operating frequency of 8.73 GHz for single elements and the integrated MIMO system when excited simultaneously.
