Abstract
A system and method for testing an adaptive RF system in an emulated RF environment using a feedback control module to efficiently and accurately evaluate the performance of the RF system under test in the search space.
Claims16
A method of testing of an RF system in a emulated RF environment comprising the steps of:
- (a) identifying at least two parameters to evaluate for an RF system, wherein a first parameter is an independent variable and a second parameter is a dependent variable;
- (b) testing the RF system by evaluating the at least two parameters across a first search space in a simulated RF environment;
- (c) determining a gradient between the first and second parameters across the first search space;
- (d) dividing the search space into a plurality of subspaces as a function of the determined gradient;
- (e) eliminating a subspace from further testing if the determined gradient for the subspace is less than a predetermined threshold;
- (f) testing the identified at least two parameters in the remaining subspaces that have not been eliminated;
- (g) continuing testing the identified at least two parameters in the remaining subspaces until a completion criteria is met.

A system for testing of an RF system in a emulated RF environment, comprising:
- a memory for storing computer readable code;
- an RF environment module operatively coupled to the memory, the module configured to emulate an RF environment in response to control instructions from a feedback control module;
- an RF system under test operatively coupled to the memory;
- a test module operatively coupled to the memory, the module configured to test the RF system by evaluating at least two parameters across a first search space in an emulated RF environment, wherein a first parameter is an independent variable and a second parameter is a dependent variable;
- a feedback control module operatively coupled to the memory, the module configured to:
- determine a gradient between the first and second parameters across the first search space;
- divide the search space into a plurality of subspaces as a function of the determined gradient;
- eliminate a subspace from further testing if the determined gradient for the subspace is less than a predetermined threshold;
- determine if a completion criteria has been met, and if the completion criteria has not been met, control the RF environment module to provide the remaining subspaces for further testing.
