Software Defined Radio aims at using the same hardware for different applications by the change in software parameters. The reconfigurable part in a Software Defined Radio is the Digital Front-end and the parameters which can be modified for different standards and technologies include bandwidth, Sampling Frequency, down converted IF, up converted IF and filter cut-off frequencies. The major goal for an ideal Software Defined Radio is to place the ADC as close to the antenna as possible. This can be achieved by Band-pass Sampling. Automatic Modulation Identification (AMI) can be used in conjunction with the design principles of Software Defined Radio to make the transceiver more flexible. The main objective of this paper is to address the concepts involved in the design of RF front end of a Software Defined Base Transceiver Station (BTS) which can be configured to support different technologies (here GSM/IS-95) depending on the software modifications. Index Terms-Automatic Modulation Identification (AMI), Base Transceiver Station (BTS), Band-pass Sampling and Software Defined Radio (SDR).978-1-4244-4067-2/09/$25.00
The present paper describes the Low-Cost Electronic Automation Unit for Plant Data Acquisition in Plant Phenotyping in which the whole system is made automatic controllable through the sensors. The image capturing of the plant that is the Plant Phenotyping process is done at different angles using a camera and a servo motor. The regular watering system is done automated by obtaining two different results of the water content of the soil present in that particular pot where the plant is present that is through Image Processing, and the Load of the Pot . Automated watering system to the Pot is done through the Solenoid water valve comparing with the results of the water content present in soil.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
