Suitability Study of Ds-uwb and Uwb-fm for Medical Applications

چکیده
In this paper, the suitabilities of direct sequence ultra wideband (DS-UWB) and ultra wideband frequency modulation (UWB-FM) are studied for medical applications. The system performances are studied by applying the measured hospital channels. The channel measurements were done at the Oulu University hospital in 2005. The measurement campaign included three different hospital environments, i.e. the operating room, intensive care unit and x-ray operating room. The measured frequency range was from 3.1 GHz to 6.0 GHz. The simulation results indicate that UWB-FM outperforms DS-UWB with low data rates, i.e. less than 1 Mbps, due to the simpler implementation. When data rate increases, DS-UWB is reasonable choice for medical applications.

In this paper, a novel CPW-fed antenna is presented for UWB applications. The antenna mainly comprises of a simple circular patch and a modified ground plane. The inclusion of two novel symmetrical rectangular slots with inner area of 3×2.8 mm2 to the top corners of the antenna creates a new path for the current and consequently leads to the bandwidth enhancement. A rectangular stub is also ado...

متن کاملNoncoherent Uwb Impulse Radio and Fm-dcsk: What Makes Them Different
For lack of empty radio bands, ultrawideband (UWB) radio system allowing reuse of already occupied frequency bands is the only solution to accommodate new wireless data communication services. Two types of UWB carriers are considered here, the frequency-shifted Gaussian pulse and chaotic signal with FM-DCSK modulation. A generalized model of transmitted reference systems is introduced first tha...
متن کاملMulti Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...
