FIELD: radio engineering. SUBSTANCE: sync signal generator produces system time signal delayed by amount of additional-channel frame shift as boundary signal of additional channel; in the process first and second integrators integrate symbols of main and additional channels, respectively, during multibeam propagation and then first and second multipliers function to multiply symbols coming from first and second integrators, respectively, in frame elements defined by boundary signals of main and additional channels. EFFECT: reduced signal delay when user is assigned additional channel. 26 cl, 11 dwg |
