AN-PRC-152(C) - Harris RF Communications - Harris Corporation

SATCOM – Satellite Communications .
SCA – Software Communications Architecture . The Software
Communications Architecture (SCA) is an open architecture
framework that tells designers how elements of hardware and
software are to operate in harmony within a software-defined
radio . SCA is a key element in the U .S . military’s Joint Tactical
Radio System (JTRS) . It governs the structure and operation of
the JTRS, enabling programmable radios to load waveforms,
run applications, and be networked into an integrated system .
A core framework, providing a standard operating environment,
must be implemented on every hardware set . Interoperability
among radio sets is enhanced because the same waveform
software can be easily ported to all radio sets .
SIMPLEX – Refers to presets that use the same frequency for
both transmit and receive .
SINCGARS – Single Channel Ground and Airborne Radio
System . VHF-Low ground-to-ground frequency hopping mode
used by the U .S . Army .
SIP, ESIP, ASIP – SINCGARS Improvement Program, Enhanced
SINCGARS Improvement Program, Advanced SINCGARS
Improvement Program .
TCM – Trellis Code Modulation . Technique used for high speed
LOS data operations (48 and 64 kbps) .
