Apparatus and method for processing an input signal

摘要

An apparatus includes a digital processing unit configured to process input signals comprising a variable number of data frequency bands. The digital processing unit is configured to set its processing frequency range for processing the input signal based on the number of data frequency bands in the input signal to be processed. Other embodiments are also disclosed.

1. An apparatus, comprising:
a digital processing unit configured to process input signals comprising a variable number of data frequency bands, wherein the digital processing unit is configured to set its processing frequency range for processing the input signal based on a number of data frequency bands in the input signal to be processed; wherein the digital processing unit is configured if further configured to generate, based on the processed input signal, an output signal comprising an output signal frequency range as defined by a desired transmission standard; and wherein the digital processing unit is further configured to:
receive the input signal, the input signal having an input signal frequency range corresponding to the output signal frequency range,set its processing frequency range in accordance with the frequency range covered by the data frequency bands, in case the number of data frequency bands covers a frequency range smaller than the output signal frequency range,frequency shift the data frequency bands to respective frequency bands in the processing frequency range,process the input signal having the shifted data frequency bands, andfrequency shift the data frequency bands of the processed input signal back to the frequencies in the output signal frequency range.
