Abstract:
1. A signal processor for digitally evaluating mobile communications reception signals compatible with a plurality of different mobile phone standards, comprising: a single clock frequency generator for processing the reception signals of various mobile phone standards; and at least one controllable decimator for transposing the reception signals sampled in a uniform time frame into standard-specific time frames; said decimator having a phase accumulator, a coefficient memory, a buffer memory, a multiplier, and an adder unit; said coefficient memory having an input, said multiplier having a first input, a second input, and an output; said phase accumulator having an output connected to said input of said coefficient memory, and said phase accumulator controlling a selection of coefficients with a predefinable control variable; said buffer memory having an input receiving input data and an output connected to said first input of said multiplier, said coefficient memory having an output connected to said second input of said multiplier, and said adder unit having an input connected to said output of said multiplier and said adder unit adding terms and outputting an addition result.
