Promwong, Sathaporn
Wireless body area network (BAN) technology is becoming an increasingly important part of the human body communication system and short range applications. Characteristic of ultra wideband impulse radio (UWB-IR) channel propagation is very important. The human body is more complex than other applications. Therefore, to understand the characteristics of the channel distribution on the human body is so important. This paper presents characteristic of channel propagation due to effect within human body and without human body for wireless applications based on measurement data. The template waveform is considered at the receiver side to maximize the SNR for evaluation. In this paper, the results are evaluated based on the extended Friis' transmission formula. This technique gives very accurate results and is very useful for the design and evaluation of UWB transmission for wireless medical applications, especially focusing on the effect of template waveform.

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.

Promwong, Sathaporn
This paper presents experimental evaluation of UWB human body transmission model for WBAN. The human body is more complex and many side than other application. Therefore, to understand human body channel is so important. The root raise cosine passband waveform is used as UWB transmitted waveform. The channels model is classified with body mass index. The body channel transfer functions on human body are measured by using vector network analyzer (VNA) at frequency 3 GHz to 5 GHz. The path loss model is show compared of average power loss and peak power loss. The results are discussed in conclusion.

This paper a study of UWB human body channel. The human body is more complex than other application. Therefore, to understand human body channel is so important. The analysis is based on the extension Friis' transmission formula that uses to characterize the WBAN channel transfer function. The rectangular passband waveform is used as UWB transmitted waveform. The channels of 5 positions on human body are measured by using vector network analyzer (VNA). The frequency channel transfer functions, power delay profile (PDP) and path loss are shown. The results are discussed in conclusion.

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).
