US 7,466,763 B2 · Address generating device and method of generating address

Abstract

An address frequency operation unit counts frequencies of occurrences of addresses output by an address conversion unit 14, and a CPU 16 rewrites an address conversion table in the address conversion unit 14 based on a comparison between the counted result and a threshold value. When the frequency of the address is lower than the threshold value, the frequency of occurrence of an output address is increased by increasing the number of input addresses corresponding to one output address. Also, distortion in an output signal which is fed back is detected and the address conversion table is rewritten so that the distortion is decreased.

Dependent claims

An address generating device in a distortion compensator which converts an electric power value of an input signal into an address and indexes a table by using an index address for a table made by converting the address, comprising:

an operation unit for counting a frequency of occurrence of the index address for a table input to the table, and for comparing the counted frequency of occurrence with a threshold value;
and
an address changing unit for changing the number of the addresses corresponding to the index addresses for a table in accordance with the comparison result between the frequency of occurrence and the threshold value.
