Efficiency Improvement of WCDMA Base Station Transmitters using Class-F power amplifiers


Muthuswamy Venkataramani



(ABSTRACT)
Universal Mobile Telecommunications Systems (UMTS) is the preferred third generation (3G) communication standard for mobile communications and will provide worldwide coverage, a convenient software technology and very high data rate. The high data rate, especially, requires the use of bandwidth-efficient modulation schemes such as Quadrature Phase Shift Keying (QPSK). But ....etc

Automated security systems are a useful addition to today's home where safety is an important issue. Vision-based security systems have the advantage of being easy to set up, inexpensive and non-obtrusive. This paper proposes an integrated dual-level vision-based home security system, which consists of two subsystems - a face recognition module and a motion detection module. The primary face recognition module functions as a user authentication device. On an event of a failure in the primary system, the secondary motion detection module acts as ....etc

THERMAL POWER STATION

The basic energy cycle involved in the plant is as follows :

Chemical Energy ---> Mechanical Energy ---> Electrical Energy

Turbine
Turbine converts the heat energy of the steam into mechanical energy.

The super heated steam works on the blades of the turbine and hence the blades starts rotating to produce the mechanical energy.
1) High pressure turbine.
2) Intermediate Pressure turbine.
3) Low pressure turbine.

ABSTRACT
Artificial intelligence in power station
Recently due to concerns about the liberalization of electricity supply, deregulation, and global impact on the environment, securing a reliable power supply has become an important social need worldwide. To ensure this need is fulfilled, detailed investigations and developments are in progress on power distribution systems and monitoring of apparatus. These are on (1) digital technology based on the application of semiconductor high-speed elements, (2) intelligent substations applyin ....etc
