A data dependent householder matrix is applied for such an update. In this paper a recursive estimate of the eigenvalue spread and misalignment of the algorithm is presented at a very low computational cost. Misalignment is found to be highly sensitive to the eigenvalue spread of input signals, output noise of the system and exponential window. Simulation results show noticeable degradation in the misalignment by increase in eigenvalue spread as well as system-s output noise, while exponential window was kept constant.}, journal = {International Journal of Mathematical and Computational Sciences}, volume = {6}, number = {12}, year = {2012}, pages = {1665 - 1667}, ee = {https://publications.waset.org/pdf/11855}, url = {https://publications.waset.org/vol/72}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 72, 2012}, }
