Signal processor and method for the system-independent digital generation of mobile communication transmit signals of different mobile radio standards

摘要

Mobile communication transmit signals are digitally generated for signal processing and/or D/A conversion of the transmit signals of different mobile radio standards. In the novel method only a single system-independent clock rate is generated and, accordingly, only exactly one clock frequency generator is arranged on the chip. For this purpose, the signal processing path of each mobile radio standard has at least one interpolator, particularly an asynchronous interpolator, for converting the transmit signals to a uniform time reference.
