Abstract:
1. A cellular radio communication system comprising a baseband and first to Nth transmitter-receivers connected by a transmission line, wherein the baseband comprises: a modulator for producing modulation signals to be transmitted from the first to Nth transmitter-receivers by a digital process; and a demodulator for demodulating digital modulation signals, which have been received by the first to Nth transmitter-receivers and undergone analog-to-digital conversion, by a digital process; and each of the first to Nth transmitter-receivers comprises: a digital-to-analog converter for converting a digital modulation signal to a modulation signal to be transmitted; and an analog-to-digital converter for converting a received modulation signal to a digital modulation signal, wherein at least one of the first to Nth transmitter-receivers and the baseband performs time-sharing processing or parallel processing on signals provided thereto, wherein the baseband further comprises: a RAKE receiver configured to receive signal data provided by at least two of the first to Nth transmitter-receivers respectively assigned to at least two cells of the cellular radio communication system, and to perform RAKE processing of the signal data.
