Abstract:

Contemporary long haul and tactical digital communications systems employ a variety of digital transmission formats. New code conversion equipment has been developed which digitally converts between different pulse code modulation formats and between pulse code modulation formats and delta modulation formats. Conversion is accomplished on wideband trunks without restoring the signal to analog baseband. The digital code conversion techniques may be applied to conventional multiplex equipment, Army tactical communications equipment, strategic communications systems, and TRI-TAC equipment. Conversions are accomplished with respect to data format, data rate, supervision and signaling formats and electrical interface. The code conversion techniques promise significant advantages in utility, performance and cost. System applications of the digital code converter are compared with other alternatives. Signal-to-quantization noise ratio measurements on channels which have undergone digital code conversion are presented. Author
