Abstract :
We present a fixed-point analysis of an adaptive eigenvector algorithm. Based on a linearized model, we derive explicit equations for the steady-state mean-square error (MSE) infinite precision computations. Simulation results are given to validate our theoretical analysis and model. Some modifications to make the algorithm fixed-point realizable are proposed and a ring-processor based implementation is discussed.
