Applications of Optical Signal Processing to Communications, Command and Control.
Abstract
This report discusses the application of optical signal processing to synchronization and decoding of spread spectrum signals. Synchronization and decoding are first characterized as correlation operations. Three distinct optical correlation techniques are discussed in the context of spread spectrum requirements: brute force shadowcasting, noncoherent correlation via pupil masks, and conventional coherent optical matched filtering and correlation. The strong and weak points of each techniques are identified. The noncoherent pupil mask technique is novel, and hence requires deeper theoretical and experimental exploration. For future work, an experimental comparison which encompasses all three competing techniques is outlined. (Author)
