SUMMARY:
In this article, we strive to present a general introduction of steganography, or concealment, as sometimes just is not known. Then we turn to data hiding in images. In considering these data hiding techniques, we have in mind, Bender's technical characteristics, such as data loss, the cover should be minimized and hidden data should be made as immune as possible attack data manipulation cover. Steganography in images really come of age with the invention of fast, powerful computers. The software is easily available from the Internet a ....etc

ABSTRACT:
To combat the performance deterioration brought by the time-varying propagation conditions and multiuser / intersymbol interference in the CDMA system, this paper proposes a novel means of adaptive equalizer based on QR Decomposition-based Recursive LeastSquare (QRD-RLS) algorithm to replace the conventional RAKE ....etc

verilog code to compute sin and cos functions using cordic algorithm

Introduction
On this page we will present the design of a sine and cosine computer.

Specification
We will assume that the input angle is represented in radians, and that it is in the range between - /2 and /2. Other angles can be handled by adding a factor first (modulo 2 ) and changing the sign of the sine and cosine result.

The floating point numbers are represented as integers. Technically, this means rounding them to a fixed number of bits, and then multiplying them ....etc

CORDIC ALGORITHM
Radar works by bouncing electromagnetic energy off a target, recording the echo and making some useful observation from the data. A fundamental problem in radar is that the vast majority of the reflected energy does not make it back to the receiver. Much of the processing in a radar system is to improve the signal to noise ratio of the received signal and maximizing range accuracy to determine the position of the target with less error. Various techniques are available to the radar engineer for the design of high range solut ....etc
