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 mo ....etc

Wireless video transmitters
Wireless video transmitters are used to send video signals over transmitters to receivers
through wireless signals enabling for a more efficient means of transmission than the hard
wired counterparts. The wireless video transmitters can be seen in different types of wireless
devices. The video transmitters and receivers are seen in video links used in construction site,
parking lot, property and golf course monitoring. They enable users to monitor for safety,
dangers and trespa ....etc

Smart Transmitters And Receivers For Under Water Communication
Underwater Free space optical communication promising alternative for Short range links. Considered to be point to point. New optical front end proposed the concept of smart transmitters and receivers. Smart Receivers is capable of detecting angle of arrival of signals. Smart transmitters electronically steers output beam towards particular direction. Estimates water quality from back scattered light.

Advantages are non mechanical pointing and tracking on a moving underwater veh ....etc

Moments and Channel Capacity of Single and
Dual-Branch Receivers Over Weibull Fading Channels



ABSTRACT

Diversity combining receivers is the well-known technique used to combat fad-
ing and improve system performance. There are several diversity reception methods
employed in digital communication receivers including maximal-ratio combining, se-
lection combining and switched diversity. Among the combining methods, switched
diversity offers one of the least complexity solution for fading mitigation and ....etc

smart transmitters and receivers for under water communicationppt

Abstract

The number of unmanned vehicles and devices deployed underwater is increasing. New communication systems and networking protocols are required to handle this growth. Underwater free-space optical communication is poised to augment acoustic communication underwater, especially for short-range, mobile, multi-user environments in future underwater systems. Existing systems are typically point-to-point links with strict pointing and tracking requirements. In this paper we ....etc
