The Determination of 3D Multiwavelet Transform

W. A. Mahmoud; M. S. AbdulWahab; H. N. AL-Taai

Volume 6, Issue 2 , August 2006, Page 28-46

  Abstract: The relatively new field of multiwavelets shows promise in removing some of the limitations of wavelets. Multiwavelets offer more design options and hence can combine all desirable transform features. In this paper several new algorithms for computing advance transforms are proposed. Firstly ...  Read More ...

Image Colorization Using Anisotropic Diffusion

A.M.S. Rahma; A. A. Hussein

Volume 6, Issue 2 , August 2006, Page 47-57

  Abstract: Adding colors to all pixels in monochrome image are difficulty performed. It requires considerable user intervention and remains a tedious, time-consuming, expensive task with no certain results. The previous methods have not the wanted color-scale and the harmony in colors used. This ...  Read More ...

Concealment of Information in Digital Image

Aladdin Jamel A. Al-Naji; Maysaa Hameed Abdul Ameer

Volume 6, Issue 2 , August 2006, Page 58-69

  Abstract: Transmission of secret information provides an interesting problem space for investigating information hiding. In this paper we present a proposed hiding system “Single and Double Hiding (SDH)”, which can be used to embed text file in digital image and all will be hide in cover image ...  Read More ...

Software Simulation of Fiber Bragg Grating In WDM

Sawsan Abdul-Majid; Saleh AL.Qaraawy; Yousra Abdul-Sahib

Volume 6, Issue 2 , August 2006, Page 70-80

  Abstract: WDM (wavelength division multiplexing) is a powerful technique available to meet the ever-increasing demand for communication bandwidth. Among the WDM techniques, the grating is widely used. Fiber gratings selectively reflect a narrow range of wavelengths; this becomes important in designing ...  Read More ...

Turbo-COFDM System over Multipath Rayligh Selective Fading Channel

Siddeeq Y. Ameen; il A.H. Hadi

Volume 6, Issue 2 , August 2006, Page 81-91

  Abstract: OFDM system operates at high speed data rate over selective fading channel. In this paper a Turbo Coded OFDM (COFDM) system was presented and simulated over Rayleigh selective fading mobile radio channel. The type of the turbo code used is a parallel concatenated convolutional code (PCCC). ...  Read More ...
