Abstract
A receiver (10) is arranged to simultaneously receive at least a first (S1) radio frequency signal having a first frequency band (1) and a second radio frequency signal (S3) having a second frequency band (3) that is at least partly overlapping the first frequency band (1). The receiver has frequency down-conversion means (32,33) for frequency down converting the at least first (S1) and second radio frequency signals (S3) to at least a first (S2) and a second (S4) lower frequency signal and multiplexing means (34) for sequentially multiplexing the at least first (S2) and second lower frequency signals (S4) into a frequency multiplexed signal (S5).
Claims9
Transceiver comprising:
- a receiver that is arranged to simultaneously receive at least a first radio frequency signal having a first frequency band and a second radio frequency signal having a second frequency band that is at least partly overlapping the first frequency band, the receiver comprising:
- signal conversion means for frequency down-converting the at least first and second radio frequency signals to at least a first and a second lower frequency signal;
- and
- multiplexing means for sequentially multiplexing the at least first and second lower frequency signals into a frequency multiplexed signal;
- and
- a transmitter that is arranged to simultaneously transmit at least a third radio frequency signal having a third frequency band and a fourth radio frequency signal having a fourth frequency band that is at least partly overlapping the third frequency band, the transmitter comprising:
- signal multiplexing means for sequentially multiplexing at least a third and a second signal into a frequency multiplexed signal;
- demultiplexing means for demultiplexing the frequency multiplexed signal into at least a third and a fourth lower frequency signal;
- and
- frequency up-converting means for frequency up-converting the third lower frequency signal into the third radio frequency signal and for frequency up-converting the fourth lower frequency signal into the fourth radio frequency signal.
Method for operating a transceiver, the method comprising:
- receiving at least a first radio frequency signal having a first frequency band and a second radio frequency signal having a second frequency band that is at least partly overlapping the first frequency band receiving further comprises:
- frequency down-converting the at least first and second radio frequency signals into at least a first lower frequency signal and a second lower frequency signal;
- and
- sequentially multiplexing the at least first and second lower frequency signals into a frequency multiplexed signal;
- and
- transmitting at least a third radio frequency signal having a third frequency band and a fourth radio frequency signal having a fourth frequency band that is at least partly overlapping the third frequency band, wherein transmitting further comprises:
- sequentially multiplexing the at least third and a fourth signals into a frequency multiplexed signal;
- demultiplexing the frequency multiplexed signal into at least a third and a fourth lower frequency signal;
- and
- frequency up-converting the third lower frequency signal into the third radio frequency signal and the fourth lower frequency signal into the fourth radio frequency signal.
