FIELD: information technologies.
SUBSTANCE: as data is sent from module of transfer into module of reception along channel, there are own losses of throughput capacity observed for channel in system of wireless communication, with high variation of channel quality by its frequency range, for which purpose the following is suggested: to assess (301) quality of each subchannel in appropriate channel; to classify (302) subchannels into several quality groups based on assessed quality; and to select (303) frequency of code for a group of quality. Then specified selected frequency of code for group of quality is used, when information word, which is to be transferred, is coded (304), at the same time subchannels are grouped into a limited number of groups, for instance, from one to four groups, depending on variation of channel quality.
EFFECT: provision of high throughput capacity with minimum expenses for transfer of signals in the form of additional service information.
