First Claim
Patent Images
1. A method for detecting a presence of an information signal comprising:
- receiving inputs;
determining an expected variance of the received inputs; and
testing, using the determined expected variance of the received inputs, a first hypothesis that the received inputs include an information signal to detect a presence of the information signal.
