Evaluation of the root mean square error performance of the PAST-Consensus algorithm

In previous work, we developed and investigated a distributed Projection Approximation Subspace Tracking Algorithm (PAST-Consensus) based on Consensus Propagation for wireless sensor networks. Preliminary simulation results showing a good tracking capability and still reduced complexity, have motivated us to evaluate the performance of the aforementioned algorithm. In this work, some simulation results will be presented comparing the root mean square error for several signal to noise ratios, as well as the error in the signal subspace given by its angle difference.
