چکیده

This paper addresses power allocation methods for multimedia signals over wireless channels. The aim of this paper is to minimize total power allocated for image compression and transmission, while the power for each bit is kept at a predetermined value. Maximum and minimum power control algorithms are proposed. In this work, an approach for minimizing the total power allocated to a multimedia like image due to source compression and transmission subject to a fixed bit source distortion using different parameters are analysed. Simulations are performed using haar wavelet over AWGN channel. Structural Content (SC), Average Difference, Normalized Absolute Error (NAE), etc are analysed. Maximum Power Adaptation Algorithm shows better performance than Conventional Power Adaptation Algorithm. Keywords— PSNR, MSE, SC, NAE, Correlation, Image formats

Statistical Performance Analysis of Unilevel Wavelet Based Power Allocation for Wireless Image Transmission using Lab View

Power control has been an effective approach for mitigating the effect of fading in the quality of signal transmission over wireless channels. The system typically involves a mechanism of measuring the quality of the channel seen by the receiver and providing such information to the transmitter to adjust the amount of transmitted power. Statistical analysis play an important role in analyzing i...

Performance Comparison of Daubechies, Biorthogonal and Haar Transform for Grayscale Image Compression

Image compression is process to remove the redundant information from the image so that only essential information are stored the storage size, transmission bandwidth and transmission time. In this paper comparative analysis of gray scale image compression is done by three different methods that are Daubechies Transform, Haar Transform and Biorthogonal Transform. Experimental results demonstrat...
