FIELD: communication systems using variable transfer process; optimizing modulation process and code repetition frequency in given hardware environment.
SUBSTANCE: in order to find most effective modulation and code repetition frequency process including code correction according to this criterion, communication system transmitter is provided with code packet coder and certain set of modulators having different modulation orders and modulating sub-packets that function as code words outputted from coder. Selector functions to select one of modulators by comparing product of modulation order by code repetition frequency which is, essentially, relationship between code packet size and number of information modulating characters and by comparing product of modulation order by code repetition frequency with threshold value.
EFFECT: enhanced effectiveness of found process.
