METHOD AND SYSTEM FOR CODE-MODULATED WAVE TRANSMISSION Russian patent published in 2002 - IPC

Abstract RU 2182745 C2

FIELD: radio communications engineering. SUBSTANCE: proposed invention is designed to provide radio communications between base station and plurality of subscriber stations using broad-band signal transmission channels. Transmission channels pass radio-frequency carrier waves modulated by various codes C_s,C_l...C_q, at least one of transmission channels is assigned priority over remaining transmission channels due to the fact that phase of radio-frequency carrier waves modulated by code C_s given transmission-channel priority is shifted through preset value relative to phase of radio-frequency carrier waves modulated by codes C₁,...C_q of remaining transmission channels. EFFECT: enhanced reliability of detecting transmission channel used with definite code on receiving end. 7 cl, 4 dwg
