ABSTRACT
Power is adapted for reducing the error in the data while transmission is carried. The Distance-based power adaptation algorithm (DPAA) uses the distance between reference bit and each bit to allocate transmitted power to each of its other bits. Thus, more transmitted power should be allocated to bits which are far from their corresponding bits. In order to avoid having very small transmitted powers for bits close to the reference bit, bits whose distance is less than a certain threshold value, the same transmitted power is allowed. The Balanced Power Adaptation Algorithm (BPAA) calculates the optimal transmission power assignment for each bit within the vector, taking into account all the neighboring bits.The algorithm sets upper and lower bounds for the power level to balance the power.In this paper,the performance of both the DBPAA and BPAA was analyzed based on the Mean Square Error(MSE),RootMeanSquareError (RMSE) and Peak Signal to Noise Ratio(PSNR).The Balanced Power Adaptation Algorithm (BPAA) shows better performance compared to Distance and Conventional Power AdaptationAlgorithm(DPAA) in terms of Mean Square Error and Image Quality.
