Abstract:

The Raytheon RDS-80 digital multiplexradio 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 Mbs 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.
