"Processes of communication between a base station cellular radiotelephone and a central cellular radio.For communication to a base station of mobile radio telephone that communicates with a central cellular radio and with a plurality of cellular radiotelephones.And communication to a central cellular radio that communicates with a base station of cellular radiotelephone communication system for radio telephone, cell phone,Cellular radiotelephone base station and central cellular radio ".Systems and procedures for the communication of cellular radiotelephone.This is coded digital downlink of a central cellular radio base station for a cellular radiotelephone and radiotelephone signals sampled descendentemente link ascenThe teeth (that is, sub Nyquist sampled on the rate of two samples per symbol) of the base station of mobile radio telephone to the central cellular radio.The radiotelephone signals are sampled descendentemente demodulados in central cellular radio and speech coded digital is modulated in base station of mobile radio telephone.A demodulation diversity can be used in the central cellular radio, for the diversity demodular radiotelephone signals sampled descendentemente in central cellular radio.By attaching itself descendentemente speech coded digital of a central cellular radio base station in a cellular radiotelephone.And calling himself upward signals sampled descendentemente radiotelephone base station cellular radiotelephone with a central cellular radio.Downlink and uplink connections narrow band may be provided between the base stations and the central cellular radio, so as to reduce the cost.In addition, since demodulation occurs in Central than in the cellular radio base stations, base stations of low cost can be provided.However, since the radiotelephone signals sampled descendentemente are transmitted from base stations to the central cellular radio.A demodulation diversity can be carried out in the central cellular radio, to thereby improve the voice quality of the mobile radiotelephone communications.
