Abstract:
1. An analog baseband processor for use in a communication device, the analog baseband processor comprising: an analog-to-digital converter configured to alternately sample a first mode input signal to output a first digital signal at a first sampling rate, and to sample a second mode input signal to output a second digital signal at the first sampling rate, wherein the first mode input signal has a first symbol frequency (FS a first decimator configured to reduce the first sampling rate of the first digital signal with a conversion factor of R a first sample rate converter configured to convert the reduced sampling rate of an output signal of the first decimator with a conversion factor of M a second decimator configured to reduce the first sampling rate of the second digital signal with a conversion factor of R a second sample rate converter configured to convert the sampling rate of an output signal of the second decimator with a conversion factor of M wherein the first sampling rate×M wherein the first symbol frequency (FS wherein the first sampling rate×M wherein the second symbol frequency (FS
