Method and apparatus for model identification and predistortion
First Claim
1. A model identification system, comprising:
- an analog to digital converter (ADC) including;
a conversion circuit configured to receive a first analog signal and generate a first digital signal including samples having a first rate by sampling the first analog signal at the first rate; and
a first digital signal processing (DSP) circuit configured to generate a second digital signal including samples having a second rate less than the first rate based on the first digital signal and a first sampling matrix,wherein the first sampling matrix is a block diagonal matrix including a plurality of diagonal blocks, each diagonal block is being a row vector including a plurality of elements.

Abstract
A model identification system includes an analog to digital converter (ADC). The ADC includes a conversion circuit configured to receive a first analog signal and generate a first digital signal including samples having a first rate by sampling the first analog signal at the first rate. The ADC further includes a first digital signal processing (DSP) circuit configured to generate a second digital signal including samples having a second rate less than the first rate based on the second digital signal and a first sampling matrix. The first sampling matrix is a block diagonal matrix including a plurality of diagonal blocks, each diagonal block is a row vector including a plurality of elements.
