FS-1016

FS-1016

FS-1016 is a deprecated secure telephony speech encoding standard developed by the United States Department of Defense.

The standard was finished 1991. The CELP algorithm is used. Unlike the vocoder used in FS-1015, CELP provides more natural speech. However, due to quite low bit rate and early development (1991), the speech quality is very noisy and below that of commercial cellular speech codec like AMR.

The bit rate of the codec is 4.8 kbit/s. The complexity of the codec is 19 MIPS. 1.5 kilobytes of RAM is needed. Frame size of the codec is 30 ms. Lookahead of 7.5 ms is also required.

The variation of CELP used in the FS-1016 is so-called ternary codebook, meaning that all excitation amplitudes are either +1, -1 or 0. The sub frame gain is calculated and sent to the receiver.

The FS-1016 is currently not used since its follower MELP provides better performance in all applications.
