ABSTRACT:
A signal processing system involving a least squares method where the system is structured around a microprocessor and includes memory zones 130, 140 and 250 which include Tables for facilitating the signal processing. Input signals are normalized before being applied to the Tables. Use of one of the Tables (130) is made easier by the normalization. The other Tables are involved in rotation processes in the selected least squares algorithm.
