CONTROL METHOD FOR ADAPTIVE MODULATION AND ENCODING IN WIRELESS NETWORKS AND APPARATUS FOR IMPLEMENTATION THEREOF

摘要

The invention relates to multichannel communication systems, in particular to communication through wireless networks with use of (OFDM). A method for control of adaptive modulation and encoding in wireless networks and a device for implementation thereof allows (by 1-3 dB) more properly considering radio signal propagation medium due to introduction of an optional parameter which takes into account a type of data transmitted through the communication channel in present time. As the parameter, a peak relation signal/interference (PSNR) is taken. Such effect is obtained due to calculation of encoding and modulation circuits’ adjustment individually for each type of data. The technical result is increase of data transmission quality.
