Patent ID: 7873331

Claim:
A method for providing a multi-path orthogonal recursive predistortion, comprising: generating a first orthogonal signal and a second orthogonal signal, wherein the first and second signals are orthogonal components of an input signal; combining, in analog by a first predistortion module, the first orthogonal signal with a first error correction signal to generate a first predistorted signal; combining, in analog by a second predistortion module, the second orthogonal signal with a second error correction signal to generate a second predistorted signal; and providing the generated first and second predistorted signals to a nonlinear device, wherein the nonlinear device generates an output based upon the first and second predistorted signals, wherein the first error correction signal is determined based upon an analysis of the output and the first predistorted signal, and wherein the second error correction signal is determined based upon an analysis of the output and the second predistorted signal.
