Abstract
Briefly, in accordance with one embodiment of the invention, a multi-mode receiver comprises a programmable baseband module to filter a modulated signal according to the characteristics of the receiving mode. The programmable baseband module may further comprise a programmable convolver capable of switching between the receiving modes of the multi-mode receiver by programming an impulse response of a filter to the programmable convolver.
Claims21
An apparatus comprising:
- a first filter having a programmable number of poles operably coupled to an input of a buffer;
- a second filter having a programmable number of poles operably coupled to an output of the buffer;
- and
- a programmable convolver operably coupled to an output of the second filter and wherein the programmable convolver is able to filter a received signal of a wireless communication system by programming an impulse response based on a characteristic of the received signal.

An apparatus comprising:
- a receiver able to receive signals from two or more wireless communication systems having a baseband module, wherein the baseband module includes an in-phase (I) channel to filter an I signal of the received signal and a quadrature (Q) channel to filter a Q signal of the received signal and wherein both I and Q channels include a first filter having a programmable frequency response, operably coupled to an input of a buffer;
- and a second filter having a programmable frequency response, operably coupled to an output of the buffer and to an input of a programmable convolver.
A method of selecting a mode of a multi-mode receiver comprising:
- receiving a signal;
- programming a first programmable frequency response to a first filter according to a characteristic of the received signal and filtering the received signal to provide a first filtered signal;
- buffering the first filtered signal to provide a buffered signal
- programming a second programmable frequency response to a second filter according to a characteristic of the received signal and filtering the buffered signal to provide a second filtered signal;
- and
- programming a programmable convolver with an impulse response of a filter based on the characteristic of the received signal and filtering the second filtered signal.
