Abstract  Abstract

FIELD: physics; radio. ^ SUBSTANCE: invention relates to wireless communication systems, more specifically to synchronised broadcast or multi-address transmission for improving quality of received transmission. During synchronised broadcasting, the same broadcast content is transmitted using signals of the same form from multiple transmitters. Each transmitter receives the same spreading code for broadcasting. In a spread-spectrum communication system with a direct communication line which is time-division multiplexed, synchronised broadcast is put into the broadcasting slot. One version of implementation uses orthogonal frequency division multiplexing (OFDM) signals for synchronised broadcasting. The OFDM receiver is then used to process the received synchronised broadcast. Another version of implementation embodies a pseudorandom noise (PN) broadcast code for use by multiple transmitters. A corrector is used to assess synchronised broadcast. ^ EFFECT: higher quality of synchronised broadcast. ^ 31 cl, 14 dwg
