in a wideband diversity radio frequency (RF) receiver comprising a plurality of receiving antennas, receiving at least one narrowband RF signal via at least one of said plurality of receiving antennas that is unused when said wideband diversity RF receiver is operating in a narrowband receiving mode.

2. The method according to claim 1, comprising amplifying said received at least one narrowband RF signal.

3. The method according to claim 1, wherein said received at least one narrowband RF signal is at least one of:

a global systems for mobile communications (GSM) signal, digital video broadcasting handheld (DVB-H) signal, global positioning system (GPS) signal, frequency modulation (FM) signal, and an enhanced data rates for GSM evolution (EDGE) signal.

4. The method according to claim 1, comprising filtering said received at least one narrowband RF signal.

5. The method according to claim 1, comprising converting said received at least one narrowband RF signal to a digital signal.

7. The method according to claim 1, comprising down-converting said received at least one narrowband RF signal to an intermediate frequency (IF) signal.

6. The method according to claim it comprising sampling said received at least one narrowband RF signal.

8. A machine-readable storage having stored thereon, a computer program having at least one code section for processing signals in a communication network, the at least one code section being executable by a machine for causing the machine to perform steps comprising:
