Title: Method and system for reducing nonlinearity
Inventor: BRAITHWAITE RICHARD NEIL
IPC: H04B1/04
Filed: 2003-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To improve the linearity of a signal generation circuit without requiring a superlinear measurement component.  <P>SOLUTION: The nonlinearity of a signal generation circuit (201) normally provided with a modulator (102) and a power amplifier (104) arranged in series is reduced by connecting a measurement circuit (203) to the output of the signal generation circuit (201) and another point along the signal line of the signal generation circuit (201). A pre-distorted signal is supplied to the input of the signal generation circuit (201). The pre-distorted input signal includes constant components and time-varying components to induce the nonlinear mode of the signal generation circuit (201) by it. The measurement circuit (203) is balanced so that the part of the pre-distorted input signal which passes through itself may not contain the time-varying components and may not induce the nonlinearity of itself. The pre-distorted input signal is adjusted so as to reduce the nonlinearity of the signal generation circuit (201).  <P>COPYRIGHT: (C)2003,JPO
