An Efficient Digital Baseband Encoder for Short Range Wireless Communication Applications

Area-efficient digital baseband module for Bluetooth wireless communications

This paper describes a small and portable digital baseband module developed for Bluetooth wireless technology. To achieve portability and the small size, much of the Bluetooth baseband layer protocols are implemented in software running on the embedded microcontroller while the minimal tasks of low-level baseband processing, UART and USB interfaces, and audio CODEC are performed on the dedicate...

Sols Technique Based Encoder for Dedicated Short Range Communication in Intelligent Transportation System Applications

A protocol which is mainly used for intelligent transportation system is the dedicated short range communication (DSRC). By this protocol the information signals which are transmitted are encoded by using either FM0 or Manchester codes. The designing of VLSI architecture is limited by the code diversity between these two codes that supports the both. Hence this paper gives a new VLSI architectu...

An Active Receiving Antenna for Short-range Wireless Automotive Communication

This paper describes an easily manufactured, reducedsize, active receiving antenna for automotive applications, which increases short-range wireless detection in the 315-MHz band. This compact antenna has an advantage over currently available antennas because can be hidden in a vehicle’s interior. The active antenna consists of a low-noise amplifier coupled to a low-profile planer meanderline p...

An Energy Efficient Digital Baseband for Batteryless Remote Control

In this paper, an energy efficient digital baseband circuit for piezoelectric (PE) harvester powered batteryless remote control system is presented. Pulse mode PE harvester, which provides short duration of energy, is adopted to replace conventional chemical battery in wireless remote controller. The transmitter digital baseband repeats the control command transmission once the digital circuit ...
