Patent ID: 8315296

Claim:
A method for testing a cellular receiver comprising: measuring a plurality of bit error levels for the cellular receiver at a given cellular frequency from among a plurality of different cellular frequencies; applying a Huber function to the measured plurality of bit error levels to generate a bit error ratio (BER) estimate for the cellular receiver based upon an iteratively-determined BER minimizer to provide a given sensitivity accuracy level; and using the BER estimate to generate a sensitivity for the cellular receiver having the given sensitivity accuracy level; wherein the Huber function is defined as: ρ k ⁡ ( f ) = { f 2 / 2 if ⁢ ⁢  f  ≤ k k ⁢  f  - k 2 / 2 if ⁢ ⁢  f  > k where k is a positive constant within a range of about 0.8 to 1.4.
