<p>1. Time division multiplex method for a digital cellular radio system with fixed transmitting-receiving stations and with mobile transmitting-receiving stations which can exchange digital communications, which are spread by a set of orthogonal symbol codes each introduced by a synchronising preamble, with the fixed stations by radio in time division multiplex with multiple access, wherein several fixed stations are controlled from one master station, of which in turn several are connected by a relay station with a telephone dialling network, characterized thereby, that the synchronising preamble is prolonged, that the entire channel burst reply in each received time slot is determined and stored in the receiving stations according to amount and phase through correlation of the incoming with the stored synchronising preamble and that the received communications signals are correlated with the channel burst reply thus determined and stored.</p> |
