Japanese Patent JP3222904

B2

The present invention relates to a signal processing circuit for the European digital cellular radio-telephone system continuously exchanging speech samples with a conversion 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 control signals to it. This circuit comprises a control operator (CO), a processor (P) which controls an audio operator (AO) and a radio operator (RO), a control operator (CO), the audio operator (AO) receiving and producing the speech samples, and transmitting them to the processor, respectively receiving them from this 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, respectively receiving them from this processor in the form of batches, the control operator (CO) routing and formatting the data, the signalling information and the signals for control of the processor (P), this processor being provided in order to carry out the digital processing of the signal, particularly in a terminal, from the information produced by the operators and to produce the information intended for the operators, and thus being unburdened of the processing operations performed by these operators.
