Abstract
A description of the research effort, performed in accordance with a National Defence (DND) sponsored Research program, is presented. Goals fixed for the program aim at achieving good quality, encryptable voice communications in the VHF and UHF mobile bands within a channel spacing of about 3 kHz. A review of the desirable performance objectives of a land-mobile tactical voice communications system is presented, and the design strategy suggested to achieve this performance is described. Implementation includes the use of techniques such as frequency domain digital signal processing of single sideband speech, speech bandwidth reduction, and linear modulation. A study, and in some cases experimental evaluation, on promising bandwidth reduction techniques was done, and a method, called the dynamic frequency band extraction technique, was developed for this application.
