huffman algorithm and adaptive huffman algorithm binary image using matlab

Consider a black and white image. This image is made up of many pixels that are all different shades of gray which have a number value corresponding to the brightness or darkness of the shade. Black is 0, white is 255, and all the numbers in between are shades of gray. So, each pixel is coded as some integer from 0 to 255. In order to encode these integers, we must use bits. A bit have a value of either 0 or 1, and the maximum number of bits needed to code any number be ....etc

Reliable Adaptive Modulation and Interference Mitigation for
Mobile Radio Slow Frequency Hopping Channels

Abstract

The Long Range Fading Prediction algorithm for
Slow Frequency Hopping (SFH) systems is proposed and demonstrated
to enable combined Adaptive Modulation and adaptive
Frequency Diversity to mitigate the effects of fading and partialband
interference. Significant performance gains are demonstrated
relative to non-adaptive methods in realistic mobile
radio SFH channels where the total ban ....etc

adaptive fuzzy k means clustering algorithm for image segmentation matlab code

Abstract

Clustering algorithms have successfully been applied as a digital image segmentation technique in various fields and applications. However, those clustering algorithms are only applicable for specific images such as medical images, microscopic images etc. In this paper, we present a new clustering algorithm called Adaptive Fuzzy-K-means (AFKM) clustering for image segmentation which could be applied on general images and/or specific images (i.e., medical a ....etc

Short-range digital voice transmission is used extensively in modern consumer electronics.
Products such as cordless telephones, wireless headsets (for mobile and landline telephones), baby monitors are to name just a few of the items that use digital techniques to wirelessly communicate voice information. Wireless environments are inherently noisy, so the voice coding scheme chosen for such an application must be robust in the presence of bit errors.

Pulse Coded Modulation (PCM) and its derivatives are commonly used in wireless consumer pr ....etc

Time-dispersive channels can cause intersymbol interference (ISI), a form of distortion that causes symbols to overlap and become indistinguishable by the receiver. For example, in a multipath scattering environment, the receiver sees delayed versions of a symbol transmission, which can interfere with other symbol transmissions. An equalizer attempts to mitigate ISI and improve receiver performance. Communications System Toolbox provides equalization capabilities using one or more Simulink blocks, System objects, or MATLAB functions.

lms algorithm adaptive beamforming matlab code

Abstract

Array processing involves manipulation of signals induced on various antenna elements. Its capabilities of steering nulls to reduce co channel interferences and pointing independent beams toward various mobiles, as well as its ability to provide estimates of directions of radiating sources, make it attractive to a mobile communications system designer. This paper presents 8-elements array with inter-element spacing /2 an optimum value to avoid grating lobes. An Adaptive beamforming is a ....etc
