Abstract
A high-performance data transmission system, incorporating an efficient discrete signal set and optimum detection techniques, has been developed. Envelope-orthogonal signals in the transmitter and matched filters in the receiver are employed; the system has been given the name Orthomatch. As instrumented now, the system requires 1.6 db more power than calculated for information recovery, and requires effectively 1 db additional power for synchronization. On a calculated basis, Orthomatch at 16 levels requires 5.6 db less power than orthogonal incoherent PCM and 1.9 db less power than biphase PCM. Calculated and measured comparison of Orthomatch and a typical PAM-FM system shows an 11.5 db power advantage for Orthomatch.
