Title: Amplifier predistortion and autocalibration method and apparatus
Inventor: SAHOTA GURKANWAL KAMAL
IPC: H03F1/32
Filed: 2005-01-14
Abstract: Methods and apparatus for amplifier AM and PM predistortion and autocalibration. AM and PM amplifier distortion can be corrected using predistortion. The AM and PM distortion characteristics of the amplifier are determined using an autocalibration technique. The amplifier characteristics can be stored in distinct look up tables (526, 712). Alternatively, the inverse of the amplifier characteristics can be stored in distinct look up tables. Signals that are to be amplified are characterized in polar format having a phase component with a normalized magnitude and a magnitude component. The phase component can be predistorted by applying the inverse of the PM distortion characteristics to the signal. Similarly, the magnitude component can be predistorted by applying the inverse of the AM distortion characteristics to the signal. The predistorted phase component can be amplified using the previously characterized amplifier. The predistorted magnitude component can be used to set the gain of the previously characterized amplifier.

Patent CA-2592875-A1 (CA)
Inventor: LAMBERT ROBERT
IPC: H04L9/32
Filed: 2006-01-18
Abstract: Accelerated computation of combinations of group operations in a finite field is provided by arranging for at least one of the operands to have a relatively small bit length. In a elliptic curve group, verification that a value representative of a point R corresponds the sum of two other points uG and vG is obtained by deriving integers w,z of reduced bit length and so that v = w/z. The verification equality R = uG + vQ may then be computed as -zR +(uz mod n) G + wQ = O with z and w of reduced bit length. This is beneficial in digital signature verification where increased verification can be attained.
