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 image transmission. Measures of tendency like mean, mode, median, kurtosis, standard deviation gives a detailed analysis of image transmitted. The proposed algorithm performs power allocation for individual bits to minimize the Root Mean Square Error (RMSE) of a 2Dsignal transmitted over AWGN channel. A gain in Eb/No is observed for the proposed power allocation method over conventional power allocation method. This gain is achieved without any increase in bandwidth.
