Abstract

The presented EVD-based subspace tracking algorithm is highly suited for VLSI-implementation. It is based on the binary data representation of the CORDIC scheme combined with the use of approximate rotations. The different modifications of the original EVD-based subspace tracking algorithm can be interlaced, i.e. the number of rotations (sweeps) executed after each rank-1-update and the number of applied best CORDIC angles can be exchanged. The simulations show that it is usually advantageous to work with π = 2 and to adjust the number of rotations/sweeps executed after each update to the specific application, since for small rotation angles (generally present in tracking applications) π = 2 already yields an almost exact rotation.
