NATO military communications require high quality voice communications for their military missions. Currently the performance of in-place voice coding algorithms is unacceptable in the harsh tactical acoustic conditions where NATO commanders operate, such as tracked vehicles or helicopters. A new generation of 2.4/1.2 kbps speech coding algorithms has been developed which far exceed the quality of service of the existing speech coding algorithms currently used by NATO. This has led to a decision by NATO to standardize a new algorithm to suit its need, through a competition. A candidate coder based on the split-band LPC (SB-LPC) principle has been developed to fit the requirements of the competition, and has been entered by Turkey in the NATO STANAG competition. Its details are presented in this paper.
