Decision feedback signal processing based on constant modulus errors for wireless sensor networks

초록

In this paper, a recursive estimation of the Euclidean distance (ED) of constant modulus errors and its application to blind algorithms based on decision feedback (DF) structures is proposed for signal processing in severe wireless channel conditions. The proposed DF algorithm based on recursive ED yields the results that the number of multiplications increases linearly with the sample size N while that of the block processing method does squarely. The results of fast convergence performance and low complexity show that the proposed DF algorithm is an efficient signal processing method for wireless sensor networks. © 2015 namyong Kim.
