Optimum receivers for detecting binary signals in additive colored Gaussian noise are analyzed and their performance evaluated in terms of bit error probabilities Pe. Implementation and practical design implications of such receivers is discussed. Evaluation of Pe receivers that are optimum for additive white Gaussian noise WGN environments but due to jamming or friendly ECM interferers, must operate in a colored Gaussian noise environment has been carried out. It was generally found that such receivers do not perform significantly worse than receivers specifically designed to operate in a colored noise environment. Examples were considered in which the colored noise interference was modeled as the output of a one-pole filter driven by WGN. Additional work has been carried out on the jamming of binary colored noise receivers using a deterministic jammer model. While this modeling assumption needs to be refined, it has been demonstrated that a power constrained jammer can seriously degrade the performance of a receiver designed to operate in a colored noise environment.
