Low Power Transmitter for Wireless Capsule Endoscope
This paper presents the transmitter circuit designed for the application of wireless capsule endoscope to overcome the limitation of conventional endoscope. The design is performed using CMOS 0.13 μm technology. The transmitter is designed to operate at centre frequency of 433.92 MHz, which is one of the ISM band. Active mixer and ring oscillator made up the transmitter and it consumes 1.57 mA ...
متن کاملSmart Antenna Investigations for Wireless Cellular Systems
The use of smart antennas in mobile radio communications cellular networks such as GSM network, to mitigate the fading effects and to increase the traffic capacity by exploiting the Spatial Division Multiple Access (SDMA) is actually of great interest. These intelligent antenna systems take advantages of both antenna and propagation technology. Smart antennas has the capability to reduce multip...
متن کاملParallel integrated receivers for multiple antenna wireless LAN systems
This thesis focuses on the design of powerand area-efficient parallel integrated receivers for multiple antenna wireless LAN systems. These receivers are part of an indoor parallel radio system that achieves 1 gigabit per second data rates and enables high bandwidth wireless communication between portable user devices and a high speed wired internet connection. Since a critical aspect for effic...
متن کاملReview of the Wireless Capsule Transmitting and Receiving Antennas
However, the particularity of the alimentary track restricts the utilization of the current available examine techniques. The upper gastrointestinal tract can be examined by Gastroscopy. The bottom 2 meters makes up the colon and rectum, and can be examined by Colonoscopy. In between, lays the rest of the digestive tract, which is the small intestine characterised by being very long (average 7 ...
متن کاملAntenna Selection in High-Throughput Wireless LAN
This paper presents a new method for implementing antenna selection in high-throughput wireless LANs (WLANs), addressing two major practical concerns: antenna selection training protocol design, and calibration to solve RF imbalance problems. Specifically, the low Doppler spread of WLAN channels enables us to train all antenna subsets by multiple training packets transmitted in burst; consequen...
