A signal processing circuit for the European digital cellular radio system continuously exchanging speech samples with a converter circuit (AD), exchanging baseband digital signals with a radio circuit (R) and exchanging data and signalling information with a control circuit (C) which also transmit control signals to it. The circuit comprises a control operator (CO), a processor (P) which controls an audio operator (AO) and a radio operator (RO), the audio operator (AO) receiving and producing the speech samples and transmitting them to the processor and receiving them from the processor in the form of groups of samples, the radio operator (RO) receiving and producing the baseband digital signals and transmitting them to the processor and receiving them from the processor in the form of batches, the control operator (CO) routing and formatting the data, the signalling information and the processor control signals, the processor (P) being adapted to apply digital processing to the signal, in particular in a terminal, on the basis of information produced by the operators and to produce the information addressed to the operators and being thus relieved of the processing operations carred out by the operators.
Signal processing circuit for a digital cellular radio system, said signal processing circuit continuously exchanging speech samples with a converter circuit (AD), exchanging baseband digital signals with a radio circuit (R) and exchanging data and signalling information with a control circuit (C) which also transmits processor control signals to it, characterized in that said signal processing circuit comprises a control operator (CO), a processor (P) which controls an audio operator (AO) and a radio operator (RO), said audio operator (AO) receiving said speech samples and transmitting them to said processor and receiving them from said processor in groups of samples, said radio operator (RO) receiving said baseband digital signals and transmitting them to said processor and receiving them from said processor in batches, said control operator (CO) routing and formatting said data, said signalling information and said processor control signals, said processor (P) being adapted to perform digital processing associated with said speech samples, in particular in a terminal, in accordance with information produced by said operators and to provide information addressed to said operators and being thus relieved of processing operations carrier out by said operators.
