ENCODING AND MODULATION FOR SERVICES OF BROADCASTING AND MULTICAST IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2009 - IPC H04J3/00 

Abstract RU 2371858 C2

FIELD: communication facilities.

SUBSTANCE: physical links, which must be transmitted in superframe, are identified, and top it there are distributed temporal intervals in superframe. Schemes of coding and modulation for each physical link are selected on the basis of its data throughput. Data for each physical link are selectively coded on the basis of code rate of outer code, for instance for Reed-Solomon code and are additionally coded on the basis of code rate of internal code, for instance for turbo code. Coded data for each physical link are displayed into modulation symbols on the basis of selected modulation scheme. Modulation symbols for each physical link are additionally are processed (for instance, OFDM- are modulated) and are multiplexed into time slices, distributed by physical link. Data, which must be transmitted by means of other method of radiocommunication (for instance, W-CDMA), are also processed and multiplexed into time slices, distributed for this radiocommunication method.

EFFECT: efficient allocation of system resources by physical links in wireless coupling system.
