Laboratory Simulation of Multipath Propagation Effects on FM Systems

A laboratory multipath simulator was developed to provide a controlled environment for the study of the nature of long delay multipath propagation interference effects on low-channel capacity FM systems, and for the evaluation of design changes on an existing system to improve its tolerance to a multipath environment. The associated laboratory program provided a valuable collection of information both in terms of multipath effects and in providing the field engineering force with a tool to confirm their findings.
