An orthogonal projection (OP) algorithm with some decorrelation properties is described. In two dimensions this OP algorithm makes a projection on a plane, rather then on a line as in the LMS (least mean squares) algorithm. The authors show that this algorithm can be changed in such a way that it can perfectly decorrelate an AR (autoregressive) input signal. In this algorithm (OPAR), an orthogonal projection on a line is made in such a way that the update is orthogonal to all its past updates. The authors introduce an efficient realization of this algorithm, the EOPAR algorithm, having LMS complexity. Simulation results are given for the different algorithms
