accepting a desired functionality expected for the wireless communication device; selecting a plurality of modules of the wireless communication device to achieve the desired functionality, wherein the selected modules include one or more of: a plurality of antennas; at least a first processing module and a second processing module, wherein the first processing module is implemented with a single processing technique, the second processing module is implemented with at least first and second processing techniques, the first processing technique in the second processing module is selected while the second processing technique in the second processing module is not selected.

2 . A wireless communication device comprising:
a plurality of antennas; a plurality of processing modules; a processor, in responding to a desired functionality expected from the wireless communication device, configured to determine a selection for an optimized performance of the wireless communication device for the functionality, wherein the selection includes one or more of the antennas, at least a first module and a second module, the first module is implemented with a single processing technique, the second module is implemented with at least first and second processing techniques, the first processing technique in the second module is selected with the selection while the second processing technique is not used in the selection.

3 . The wireless communication device as recited in claim 2 , wherein a selection of the desired functionality is made by a supplier of the wireless communication device, a vendor of a wireless network product or an end user of the wireless communication device.

4 . The wireless communication device as recited in claim 3 , wherein the first and second processing techniques are blind techniques or non-blind techniques.

5 . The wireless communication device as recited in claim 3 , wherein the functionality includes one or more of: a maximum range the wireless communication reaches, a quality of a transmission link the wireless communication device establishes with another device, an ability of providing multipath mitigation and interference suppression, a desired capacity of the wireless communication device, a desired power consumption of the wireless communication device, one of protocols supported in the wireless communication device, one of modulation techniques used in the wireless communication device, and one of processing techniques for combining signals received in the wireless communication device.

6 . The wireless communication device as recited in claim 2 , wherein the selection is optimized by providing selected features that are only needed to support the desired functionality.

7 . The wireless communication device as recited in claim 5 , wherein some of the processing modules are integrated circuits, and the processor is configured to modify a complexity of antenna integrated circuits by turning on or off some functions of the integrated circuits and a selection of processing techniques used with the antenna integrated circuits such that a vendor or user of the wireless communication device needs only to purchase or license functions needed for achieving the desired functionality.

8 . The wireless communication device as recited in claim 6 , wherein the selection is so determined that the wireless communication device is capable of providing a varied operating range in a multipath environment.

9 . The wireless communication device as recited in claim 8 , wherein each of the single processing technique, the first and second processing techniques is related to a maximal ratio combining (MRC) technique, equal-gain combining technique, a minimum mean square error (MMSE) combining technique.

10 . The wireless communication device as recited in claim 7 , wherein the selection includes at least two of the antennas.

11 . The wireless communication device as recited in claim 10 , wherein each of the antennas is associated with a RF chain, the at least two of the antennas are selected through selection diversity based on a signal received from each of the antennas.

12 . The wireless communication device as recited in claim 11 , wherein the at least two of the antennas are selected to provide a desired power consumption.

13 . The wireless communication device as recited in claim 12 , wherein when the received signal falls into a range requiring multiple antennas, the at least two antennas are activated to provide a higher signal-to-noise ratio (SNR).

14 . The wireless communication device as recited in claim 6 , wherein the selection is so determined that the wireless communication device is able to suppress signal interference.

15 . The wireless communication device as recited in claim 6 , wherein the selection is so determined that the wireless communication device is controlled to have a varied level of power consumption.
