Hayre, Harbhajan S.2022-09-232022-09-23196713869149https://hdl.handle.net/10657/11997Several sets of orthonormal functions suitable for use in orthogonal multiplexing systems were derived. The functions were selected on the basis of ease of implementation since orthogonal multiplex systems perform equally well for all signal waveshapes in channels with additive white Gaussian noise. The functions were analyzed and mathematical relationships were derived for message distortion due to time, frequency, and amplitude truncation. The orthomux system was also simulated on an IBM 7090 digital computer using the DSL-90 simulation language to evaluate the effects of realistic channel models. The computer programs used in this simulation are described. [...]application/pdfenThis item is protected by copyright but is made available here under a claim of fair use (17 U.S.C.
