Using the proportionate-type steepest descent algorithm we represent the current weight deviations in terms of initial weight deviations. Then we attempt to minimize the mean square output error with respect to the gains at a given instant. The corresponding optimal average gains are found using a water-filling procedure. The stochastic counterpart is obtained in two steps. First, the true weights,...
The subband system identification method consists of identifying a linear system in the time-frequency domain. This technique can be also used to approximate a linear system in the same domain. In both cases, it has the advantage of having a very high numerical efficiency; however, analyzing such a technique is not trivial, and the best setup for subband system approximation and identification is...
