Digital Transmission Evaluation Project. RDS-80 Test.
Abstract
The Raytheon RDS-80 digital multiplex/radio system was tested in back-to-back and actual link configuration for determination of transfer parameters and to develop standard test techniques. The system has a maximum propagation rate of 40.15 Mb/s (600 voice channels) in a 40 MHz bandwidth in the 11 GHz band BER vs RSL characteristics are displayed and analyzed as the primary mode of equipment evaluation. Actual link data is presented for analysis of cross-polarization characteristics and fading. Carrier-to-interference data, T1 line tests and theoretical predictions are compared. Multiple-hop conditions were simulated. Power spectral density characteristics are compared to FCC spectrum requirements. Concepts of link BER availability are presented.
