Abstract:
1. A method comprising: receiving a Radio Frequency (RF) Multiple Frequency Bands Multiple Standards (MFBMS) signal having a plurality of information signal frequency bands and corresponding to a plurality of communication protocols; for a first set of information signals of the RF MFBMS signal, down-converting the RF MFBMS signal by a first shift frequency to produce a first baseband/low Intermediate Frequency (BB/IF) MFBMS signal, the first shift frequency based upon at least a first communication protocol corresponding to the first set of information signals; for a second set of information signals of the RF MFBMS signal, down-converting the RF MFBMS signal by a second shift frequency to produce a second BB/IF MFBMS signal, wherein the second shift frequency differs from the first shift frequency, and down converting the RF MFBMS signal by the second shift frequency causes at least one information signal frequency band of the BB/IF MFBMS signal to be shifted below zero frequency, the second shift frequency based upon at least a second communication protocol corresponding to the second set of information signals; combining the first and second BB/IF MFBMS signals to produce combined BB/IF MFBMS signals; high pass filtering the combined BB/IF MFBMS signals to remove the at least one information signal frequency band that is shifted below zero frequency; and extracting data from the combined BB/IF MFBMS signals corresponding to a plurality of differing communication protocols.
