Abstract

Common path time and frequency domain optical adaptive linear predictors are disclosed, characterized by wide bandwidth operation for use in channel equalization, source redundancy removal, speech encoding, and other areas. The predictors are noninterferometric, avoiding the instability of such processors in the prior art.
