Wireless Video Transmission with Maximum Power Adaptation Algorithm and Convolutioncode Rate-1/2 using Lab View

G. Naveen Kumar; M. Padmaja; K. Prasuna

In this Paper, Power is controlled by reducing the error in the data while transmission is carried .This transmission takes place by bits. The proposed algorithm was based on updating the amount of power transmitted for each bit according to its importance in the Video quality as measured by the mean-square error. This Maximum Power Adaptation Algorithm along convolution coding is used to find the optimum power distribution vector such that the RMSE is minimized subject to the constraints that the power per bit is kept constant considering Maximum Root Mean Square Error using Lab view. The above optimization is done for RMSE regardless of the average probability of bit error and the PAPR is kept below a certain limit. Maximum Power Adaptation Algorithm shows better performance compared to the case of Conventional power adaptation while reducing the peak-to-average Power (PAPR) ratio.
