High Speed Downlink Packet Access (HSDPA) – A Means of Increasing Downlink Capacity in WCDMA Cellular Networks
Abstract:
The increasing demand for capacity in order to provide high data rate multimedia services in wireless environments necessitates enhanced radio transmission techniques and network protocol functionality. Such techniques have to be added to already existing mobile cellular networks, e.g. as provided by EDGE. For 3rd generation UMTS networks based on WCDMA, the High Speed Downlink Packet Access (HSDPA) is bein ....etc

HIGH CAPACITY,LOSSLESS,SECURE IMAGE STEGANOGRAPHY USING WAVELETS




IMAGE STEGANOGRAPHY

Steganography means – “COVERED WRITING”.

It’s a concealed communication

Image steganography is the technique hiding a payload (message) is hided
inside cover image (carrier),to get a stego-image.

Cover image is not statistically changed.

The modern example of steganography is a microdot.


DRAWBACKS….

A Novel 4-Level Converter for High Speed SR Drive
This paper proposes a novel 4-level converter and
instantaneous switching angle detector for a high speed SRM
(Switched Reluctance Motor) drive. The excitation current cannot be sufficiently built up . the demagnetization
current can be easily extended to the negative torque region.The 4-level converter proposed here has additional charge capacitor and an active power switch compare than a conventional asymmetric converter. the high charged voltage of additional capacitor is supplied to the ....etc

HIGH CAPACITY AND SECURITY STEGANOGRAPHY USING
DISCRETE WAVELET TRANSFORM



Abstract

The secure data transmission over internet is achieved using Steganography. In
this paper High Capacity and Security Steganography using Discrete wavelet
transform (HCSSD) is proposed. The wavelet coefficients of both the cover and
payload are fused into single image using embedding strength parameters alpha
and beta. The cover and payload are preprocessed to reduce the pixel range to
ensure the payload is recovered a ....etc
