Patent ID: 7936288

Claim:
A handheld, wireless communication device, comprising: a baseband processor that includes an audio codec, a digital signal processor (DSP), a core processor and a memory, the audio codec being operatively coupled to the DSP, the DSP being operatively coupled to the memory, the core processor being operatively coupled to the memory, the memory being shared by the DSP and the core processor, wherein the baseband processor is configured to support multiple wireless communication protocols and multiple antennas, wherein the baseband processor is configured to support separate processing paths for at least a general audio path, a voice path and a polyphonic ringer path before mixing the supported, separate processing paths, wherein the baseband processor is configured to decimate a multi-level digital input signal by M, where M is an integer that is greater than or equal to 2, and wherein the baseband processor is configured to generate an output digital signal having a number of signal levels greater than the multi-level digital input signal by processing the decimated multi-level digital input signal.
