Example communication system 100 can comprise first radio module 110, and it is used for receiving at least one signal of communication by antenna 105.Following discussion is generally discussed the signal of communication that receives as wireless signal (for example, RF signal).But the signal of communication of reception can comprise the feature of any signal relevant with various communication mediums (as wired signal, RF signal, wired light signal, wireless optical signal etc.).Therefore, first radio module 110 can comprise any radio hardware and/or the Characteristic of Software relevant with these signals.
Therefore, as discussed below, antenna 105 can be corresponding to one or more antennas.Such as but not limited to, antenna 105 can be corresponding to single antenna, perhaps corresponding to many antenna configurations.For example, described many antenna configurations can be used for beam shaping configuration, perhaps multiple-input, multiple-output (MIMO) configurations (for example, according to IEEE802.11 (n) multi-antenna communication).
First radio module 110 can be used for receiving at least one signal of communication that transmits according to any communication protocol (as wireless or wired computer network or communication network agreement). Such as but not limited to, first radio module 110 can receive the signal of communication according to arbitrary in GSM/GPRS/EDGE, CDMA, WCDMA/UMTS, TDMA, PDC, DVB-H, IEEE 802.11, IEEE 802.15, IEEE 802.16, bluetooth, Zigbee, ultra broadband, Ethernet, token ring, agreement standard and/or proprietary etc. or all protocol transmission.

And for example, second radio module 120 can be used for receiving relevant with various communication mediums and/or according to the signal of communication of any communication protocol.
In a non-circumscribed exemplary arrangement, first radio module 110 can be used for receiving Bluetooth signal, and second radio module 120 can be used for receiving WLAN signal (or Bluetooth signal and WLAN).In another non-circumscribed exemplary arrangement, first radio module 110 can be used for receiving cellular phone signal (for example, GSM or CDMA signal), and second radio module 120 is used to receive the radio computer network signal.In the another one exemplary arrangement, first radio module 110 is used to receive the CDMA signal, and second radio module 120 is used to receive the GSM signal.

The various exemplary communication device with discussing shown in exemplary communication device 100 shown in Figure 1 and the application generally comprise first and second radio modules.The configuration of this two radio modules is used to illustrate, rather than the scope of each side of the present invention is restricted in the configuration of the radio module with specific quantity.Scope of the present invention is easy to expand to the configuration that comprises more than two radio modules (for example configuration of three, four or N radio modules, wherein N is a positive integer).
To note equally, though first radio module 110 and second radio module 120 (and various radio modules described here) show with standalone module, but first radio module 110 and second radio module 120 can be independently of one another fully, also can share a plurality of parts.Such as but not limited to, first radio module 110 and second radio module 120 can be shared various amplifiers, mixing and frequency generating circuit.Fig. 2 shows this part or integrated completely, and will provide introduction in the back.
Therefore, according to configuration, first radio module 110 and second radio module 120 can be side by side or are sequentially received the corresponding communication signal.This reception simultaneously or sequentially will more be discussed in conjunction with the communication device configured shown in the back.Therefore, scope of the present invention and essence are not subjected to side by side or sequentially to receive the restriction of the feature of corresponding communication signal.
Exemplary communication device 100 can also include shared filter 130.For example, the filter 130 of Gong Xianging can be connected to first radio module 110 and second radio module 120 communicatedly.For example, first radio module 110 can be exported to first receiving communication signal 111 filter 130, the second radio modules 120 second receiving communication signal is exported to filter 130.For example, this communicating to connect can be realized by direct or indirect connection.Shown in Fig. 7-9, this communicating to connect can be realized by various parts (for example, interchanger, signal combination circuit, multiplexer etc.) between two parties indirectly.
The filter of sharing 130 can carry out filtering to signal of communication according to any selectable (for example, programmable) filter response feature.For example, described shared filter 130 can carry out filtering according to one group that the selects signal of communication that at least one radio module from first radio module 110 and second radio module 120 is received from many groups of selectable filter response features.In a non-circumscribed exemplary arrangement, first group in the selectable filter response feature of described many groups corresponding to first communication protocol, and second group corresponding to the second communication agreement.
This selectable (for example, programmable) filter response feature can comprise any selectable filter response feature.Such as but not limited to, described filter response feature can comprise the filter center frequency.In a non-circumscribed exemplary scenario, first group of filter response feature can comprise first centre frequency, and second group of filter response feature can comprise second centre frequency.Again for example, described filter response feature can comprise that filter ends (or turning) frequency.In a non-circumscribed exemplary arrangement, first group of filter response feature can comprise first cut-off frequency, and second group of filter response feature can comprise second cut-off frequency.
In addition, for example, described filter response feature can comprise bandwidth.In a non-circumscribed exemplary arrangement, first group of filter response feature can comprise first bandwidth, and second group of filter response feature can comprise second bandwidth.Again for example, described filter response feature can also comprise stopband attenuation.In a non-circumscribed exemplary arrangement, first group of filter response feature can comprise first order stopband attenuation, and second group of filter response feature can comprise second level stopband attenuation.Again for example, described filter response feature can comprise passband fluctuation.In a non-circumscribed exemplary arrangement, first group of filter response feature can comprise first order passband fluctuation, and second group of filter response feature can comprise second level passband fluctuation.
In a word, this selectable (for example, programmable) filter response feature can comprise any filter response feature relevant with filter.Therefore, the scope of various aspects of the present invention should not be subjected to the limitation of any specific filter response feature.
As mentioned above, first radio module 110 and/or second radio module, 120 exportable corresponding RF signals of communication, IF signal of communication or baseband communication signal.Therefore, the filter 130 of Gong Xianging can be used for the signal of any above-mentioned communication signal type is carried out filtering.To the exemplary communication device configuration relevant with this filter be shown among Fig. 3-6.
For example, the filter 130 of Gong Xianging can comprise the feature of programmable analog filter.Such as but not limited to, the filter of sharing 130 is programmable (perhaps adjustable), by various passive electronic components (as resistor, capacitor, inductor etc.) are switched to or switch filter circuit and realize.For example, described switching can use various types of switches (for example, traditional semiconductor switch, microelectronic mechanical switch (MEMS) etc.) to realize.For example, the filter 130 of Gong Xianging can include the exchanging array (for example, one or more ladder networks) of passive component.In so a kind of exemplary configuration, the configuration of first switch can be corresponding to first group in the selectable filter response feature of many groups, and the second switch configuration can be corresponding to second group in the selectable filter response feature of many groups.
Again for example, the filter 130 of Gong Xianging can be realized (or adjustable) able to programme by switching between each filter of filter exchanging array.In so a kind of configuration, the total filter response that can select the one or more filters in this filter exchanging array to obtain to want.In such exemplary configuration, the configuration of first switch can be corresponding to first group in the selectable filter response feature of many groups, the second switch configuration can be corresponding to second group in the selectable filter response feature of many groups, and the configuration of the 3rd switch can be corresponding to the 3rd group of the selectable filter response feature of many groups.
Again for example, the filter 130 of Gong Xianging can be realized (or adjustable) able to programme by tuning one or more tunable passive electronic components.For example, described tunable passive electronic components comprises the feature of any tunable passive component (for example, adjustable MOSFET resistor, adjustable condenser etc.).Under so a kind of configuration, the tuning of first passive component can be corresponding to first group in the selectable filter response feature of many groups, and the tuning of second passive component can be corresponding to second group in the selectable filter response feature of many groups.
Again for example, the filter 130 of Gong Xianging can be realized (or adjustable) able to programme by the sequential (timing) of regulating various signals.Such as but not limited to, the filter of sharing 130 can use the active charge transfer, and (Active Charge Transport, ACT) equipment postpones with control signal.Under so a kind of configuration, first signal delay can be corresponding to first group in the optional filter response feature of many groups, secondary signal postpones can be corresponding to second group in the optional filter response feature of many groups, and the 3rd signal delay can be corresponding to the 3rd group of the optional filter response feature of many groups.
For example, the filter 130 of Gong Xianging also can comprise the feature of various programmable digital-filters.Such as but not limited to, the filter of sharing 130 can comprise a plurality of taps with programmable coefficients.Again for example, the filter 130 of Gong Xianging can include the whole tap of adjustable number.Again for example, the filter 130 of Gong Xianging can dispose in (between for example, finite impulse response (FIR) (FIR) and infinite impulse response (FIR) configuration) between the various filter configuration again.Fig. 5 and Fig. 6 will illustrate the exemplary communication device configuration that comprises digital filter.
In a word, share the feature that filter 130 can comprise any adjustable (for example, programmable) filter.Therefore, scope of the present invention is not subjected to the restriction of feature of the filter of any particular type.
Exemplary communication device 100 can include FILTER TO CONTROL module 132.For example, in the FILTER TO CONTROL module 132 optional majority group filter response features one group, and the filter 130 that indication is shared carries out filtering according to selected filter response feature to signal of communication.
Is what to separate in the FILTER TO CONTROL module 132 shown in Fig. 1 with filter 132.This independence is in order clearly to give an example, and does not mean that it is essential.For example, FILTER TO CONTROL module 132 can partly or wholly be integrated into and share in the filter 130.Such as but not limited to, can realize various FILTER TO CONTROL functions by shared filter 130, and realize various other FILTER TO CONTROL functions by the processor of executive software instruction and/or by state machine.Other exemplary communication device shown in Fig. 2-9 are integrated into the function of FILTER TO CONTROL module 132 to be shared in the filter 130, but this integrated only be example.
FILTER TO CONTROL module 132 can instruct the operation of sharing filter 130 in many ways.Such as but not limited to, FILTER TO CONTROL module 132 can include memory device, and this memory device, stores is switched setting with the corresponding programmable filter of the special filter response feature group of selecting.After selecting one group of specific filter response feature (for example, selecting the one group of corresponding specific filter response characteristic of signal of communication with the reception of particular type), corresponding filter switches the switching device that can be applicable to shared filter 130 is set.For example, described switching setting can be shared one group of specific passive component, subfilter or other the filter element of the response characteristic of filter 130 corresponding to management.
Again for example, FILTER TO CONTROL module 132 can include memory, and described memory stores is used for the information of the passive component of tuning shared filter 130.Selected after one group of specific filter response feature, corresponding passive component tuning information will be applied to share in the tunable passive device of filter 130.Again for example, FILTER TO CONTROL module 132 can be stored the information relevant with the digital filter tap coefficient.After selecting one group of specific filter response feature, corresponding filter tap coefficients is applied to sharing in the tap of filter 130.Again for example, but FILTER TO CONTROL module 132 memory filter configuration informations.After having selected one group of specific filter response feature, will use corresponding filter configuration information to revise the configuration of sharing filter 130.
FILTER TO CONTROL module 132 is the selective filter response characteristic in any manner.Such as but not limited to, FILTER TO CONTROL module 132 can be selected a group in the optional filter response feature of many groups at least in part based on the indication of the signal of communication that receives corresponding to specific communication protocol.Again for example, FILTER TO CONTROL module 132 can be at least in part based on the signal of communication of determining to be received whether corresponding to the decision of specific communication protocol, select groups in the selectable filter response feature of many groups.
Again for example, FILTER TO CONTROL module 132 can be described (operating profile) based on predefined communication process or operation at least in part, selects a group in the selectable filter response feature of many groups.Again for example, FILTER TO CONTROL module 132 can be at least in part based on user's request or (for example from another communication system, communication network controller, access point or other communication equipments) request that receives, select groups in the selectable filter response feature of many groups.
In a word, FILTER TO CONTROL module 132 can be selected one group of filter response feature, and guides shared filter 130 according to selected filter response feature signal of communication to be carried out filtering.Therefore, the scope of various aspects of the present invention is not subjected to any ad hoc fashion of selective filter response characteristic or carries out the restriction of any ad hoc fashion of filtering according to the filter response feature control filters of having selected.
Now the various features of exemplary communication device 100 (and the application will discuss other communication equipments) will be described by non-limitation embodiment.
In the first nonrestrictive exemplary arrangement, exemplary communication device 100 (for example can comprise the first signal of communication path, comprise first radio module 110 and shared filter 130), receive and handle the signal of communication corresponding by this first signal of communication path with first communication protocol.Communication equipment 100 also (for example can include the second communication signal path, comprise second radio module 120 and the filter of sharing 130), by this second communication signal path reception and the processing signal of communication corresponding with the second communication agreement, and described second communication agreement is different with described first communication protocol.Such as but not limited to, the described first signal of communication path can be partly different with the second communication signal path, but shared shared filter 130.
In this exemplary arrangement, when handling the signal of communication related with the first signal of communication path, the shared filter 130 foundations filter response feature relevant with first communication protocol is to signal of communication filtering.When handling the signal of communication related with the second communication signal path, the shared filter 130 foundations filter response feature relevant with the second communication agreement is to signal of communication filtering.Handle at the same time among the embodiment of the signal of communication related with the first and second signal of communication paths, share filter 130 can according to all related filter response characteristic processing merging of first and second communication protocols after signal of communication.
Fig. 2 is the partial schematic diagram according to the of the present invention second exemplary multimode communication device 200.Such as but not limited to, exemplary communication device 200 can be shared any or all features with shown in Figure 1 and above-mentioned exemplary communication device 100.
