ISSN: 0975 – 6779| NOV 12 TO OCT 13 | VOLUME – 02, ISSUE 02| Page 838 Abstract This paper focuses on Embedded Zero Tree Wavelet coding for Image transmission over wireless channels with maximum power adaptation. The objective is to minimize total power allocated for image compression and transmission, while the power for each bit is kept at a predetermined value. In this Paper, an approach for minimizing the total power adapted in a multimedia like image due to source compression and transmission subject to a fixed bit source distortion is considered. Simulations are performed using Embedded Zero Tree Wavelet (EZW) over AWGN channel using QPSK modulation. The numerical analysis shows that optimized power methods can reduce the total Power Adapted by a significant factor and the Bit error rate is reduced considerably compared to the Conventional Power Adaptation method.

We have developed, in the framework of the HICAM project supported by EC, two Anger cameras, with 5x5 cm and 10x10 cm FOV. They offer a high intrinsic spatial resolution (<1mm), an overall spatial resolution of ~ 2.5 mm @5cm and appropriate sensitivity. The cameras are based on the use of a matrix of Silicon Drift Detectors (SDDs) coupled to a CsI(Tl) crystal. The cameras are compact, very vers...
