This research paper presents indoor localization using weighted localization algorithm (WLA) with impulse radio for ultra-windband. The ultra-wide band is wireless technology short range system, especially in, an indoor localization. In this paper, the proposed process consists of two parts: Firstly, a data collected by measurement environment in a Line-of-Sight using impulse radio and secondly extension weighted localization algorithm with wireless ultra-wideband (WUWB) for localization short-range system in an indoor environment. Its can be improve the distance error. The results are evaluated by the cumulative distribution function to check a probability of distance error. The results provided good improvement which increase the wireless indoor localization precision less than 1 m. The proposed WLA for WUWB localization can be used in various applications for the wireless indoor environment.

The combination of ultra-wideband and wireless human body application is a promising communication system for future wireless system in short range. In particular, wireless body area network is based on IEEE 802.15.6. Therefore, the effect with human body is very important to know a channel characterization. In this paper, the ling of sight and non-line of sight scenario have been presented. The measurement is coverage as a full-band of FCC regulation which is 3.1 GHz to 10.6 GHz and include the under test antenna and vector network analyzer is provided. In order to investigate some of parameter, path loss and power delay profile are discussion.

The modern technology of wireless communications is rapidly developed and apply with short range communication networks around human body. The related research in these application has been investigating. In order to study the effect of human body in the high speed data rate technology, the patterns of ultra wideband for body area network has been studied. The measurement results have been measure and collected by vector network analyzer and analyze by using the equation of Friis. The proposed model is design for test and measure with human body in an indoor environment. The results show the usefulness information for a wireless communication for human body area network with ultra wideband.

The body area network (BAN) working on IEEE 802.15.6 is a wireless short-range communication system that is smaller in coverage than the personal area network (PAN) IEEE802.15.3a. A wireless body area network (WBAN) is a wireless technology with a human body that is becoming a key part of short-range radio wave systems and wireless medical technology. The transfer function characteristics of the human body and the transmission loss due to the human body should be studied. Short-range radio wave applications with a human body are more complicated than additional uses. Therefore, realizing the distribution channel characteristics of the human body with ultra-wideband (UWB) technology is important. UWB technology has a very large bandwidth, low power, and low cost, which can be used in shortrange systems. In this paper, we present the characterization measurement data of the UWBHB channel transfer function based on the human body effect with and without human body in WBAN system. In this study, we maximize the signal-to-noise ratio (SNR) and contemplate the matched filter at the receiver. The outcomes are analyzed and evaluated on the basis of Friis' formula. The proposed method achieves very precise results and is convenient for the evaluation and design of the waveform of WBAN transmission in wireless medical applications and BAN systems, mainly focusing on the input waveform effect.

An ultra wideband impulse radio (UWB-IR) are developing to use in communication system and medical application because it has been an increase interest in using on body for health monitoring and body area networks (BAN). This research want to improving UWB channel propagation on body by using CLEAN algorithm for eliminate noise in channel propagation. In addition to, we use result from previous work for easier to compare performance before system. Moreover, in this paper us analysis performance of system when using CLEAN algorithm and compare without use CLEAN Algorithm by us will show BER in each position on body for analysis performance of CLEAN algorithm can be reduce noise or effect on body when without CLEAN Algorithm. © 2013 Springer Science+Business Media Dordrecht(Outside the USA).

This paper presents the evaluation of the transmission gain of an ultra wideband antenna on a labtop computer based on the extended Friis' transmission formula. The matched filter is considered at the receiver side to maximize the SNR for evaluation. This technique gives very accurate results and is very useful for the design and evaluation of UWB impulse radio transmission systems, especially for the evaluation of waveform distortion effects. ©2009 IEEE.
