Nd. Stojanovic et al., NONUNIFORM DELTA-MODULATION FOR CODING OF THE SERVICE CHANNEL IN OPTICAL-SYSTEMS, International journal of electronics, 75(4), 1993, pp. 601-605
A new algorithm for non-uniform delta modulation is presented. It is c
alled statistical delta modulation (SDM) due to the statistical nature
of clock instants. SDM is especially suitable for the modulation of t
he service channel based on the line code redundancy, where no other k
nown delta modulation with uniform clock can be applied. SDM and linea
r delta modulation (LDM) are compared by computer simulation.
