Claim One:
1. A method for estimating values for respective complex factors of a set of complex factors for predistorting a power amplifier, the method comprising: selecting a complex factor from the set of complex factors for a computation interval in accordance with a selection criterion that is reevaluated in each of consecutive computation intervals; estimating a solution value for the selected complex factor during the computation interval by an iterative computation that constrains the estimated solution value towards a final solution value over an arbitrary number of iterations that is unbounded by the duration of the computation interval; computing a cumulative error in the estimated solution value at each iteration of the iterative computation over the consecutive computation intervals independently of which complex factor from the set is the selected complex factor at each iteration; determining from the cumulative error whether a convergence criterion is met; and terminating the estimating upon the convergence criterion being met independently of the solution value estimated for any one of the complex factors in the set.
