| dc.description.abstract | Abstract: Communication plays a crucial role in
the context of military operations. The Revolution
of Hand-Held radio from Analogue to Digital
Technology reached up to many advanced radios
with the application of Modern Technology. A
famous means of communication which is utilized
in modern military warfare is Digital Mobile
Radio (DMR). However, due to highly expensive
DMRs, it cannot be easily catered to suit various
requirements. This paper aims to discuss the first
Hand-Held DMR designed and developed for the
Sri Lanka Military named the Creeper (The unique
bird who can sing vast frequency bands). Creeper
aims to reduce the capital cost investment on
expensive DMR and provide flexibility for future
improvements. The Creeper DMR is checked
against existing DMRs such as Racal Cougar,
tested on the field, and made many improvements.
A Voice Coder (Vocoder) is used to meet the VHF
frequency bands designed and then further
developed to work on both VHF and UHF bands.
The test results were satisfactory in the field and
are currently same being used by Tri-services in
Sri Lanka. Creeper has successfully provided a
cost-effective solution and would stand out as
possible future foreign market | en_US |
