DEB Stage 1 - CONUS Link Testing.

Abstract

CONUS link testing was initiated to establish a data base and performance assessment of a similar microwave system in advance of the final implementation of the DEB Stage-1 program. Six AN/FRC 162 radios, two AN/FRC 165 radios, and ten T1-4000 multiplexers were used to establish four terminals with the capability of propagating over eight paths, one of which had a length of 82 miles. Long term results show a close correlation of measured and predicted signal levels. A large difference was noted in the number of fades recorded at each terminal receiver, over one path. The BER was 1.85 x 10 to the minus 8th power after eight transmission links of baseband repeaters. Variability among multiplexer sensitivities was important in determining the distribution of errors in the baseband repeater tests. A baseband Degradation Monitor was found to be suitable for use on a one hop transmission system. (Author)
