US 7,466,762 B2 · Distortion compensating apparatus

Abstract

A distortion compensation apparatus shortens the time until start of the transmission. The distortion compensating apparatus for amplifying the transmitted signal after implementation of the distortion compensation process thereto comprises a coefficient memory operable to store coefficients used for the distortion compensation process, an initial value memory operable to store the initial values of the coefficients, and a controller which controls the coefficient memory to store, with limitation, only the coefficients corresponding to the first portion among those stored in the initial value memory for the initial write to the coefficient memory and to store thereafter the coefficients corresponding to the second portion.

A distortion compensating apparatus for amplifying and transmitting a signal after a distortion compensation process is performed thereto, comprising:

a coefficient memory configured to store coefficients used for the distortion compensation process;
an initial value memory configured to store initial values of the coefficients;
and
a controller configured to control, the coefficient memory to store, for an initial write to the coefficient memory, only coefficients corresponding to a first portion of coefficients stored in the initial value memory and also controlling thereafter the coefficient memory to store coefficients corresponding to a second portion of coefficients stored in the initial value memory.
