In for multiple signals distributed communication covering method include to the distribution covering method of downstream signal and to upward signal
Distribution covering method.Both transfer control methods are illustrated individually below.
The downstream signal refers generally to send the signal for transmitting to antenna 45 and carrying out descending covering from base station 1, when one or
During the correspondence multiple antenna 45 of multiple base stations 1, multichannel downstream signal is formed.To the distribution of downstream signal in the utility model embodiment
Comprised the following steps in the embodiment of formula communication overlay method：
Step S11, baseband signal is modulated to after at least two-way radiofrequency signal for receiving is combined, and by the modulation
Combining signal downlink transmission afterwards.
After the radiofrequency signal that at least two route base stations 1 that the surface units 2 will be received send is combined, pass through
First radio-frequency module 21 carries out down-converted and is converted to intermediate-freuqncy signal, then carries out down-converted by the first ifd module 22
The intermediate-freuqncy signal is modulated to baseband signal, to reduce image frequency interference, the digitlization of downstream signal is realized, then by institute
Downlink transfer is stated after frame format framing of the baseband signal for obtaining by the first frame processing module 23 by predetermined protocol to being classified list
First 3a.Preferably, the framing process includes being set according to predetermined frame format the destination address of the signal.
Step S12, will transmit the combining signal branch come and goes out the first baseband signal of present node and continue traveling downwardly biography
It is defeated.
The first stage unit 3a is received after the combining signal that transmission comes, on the one hand, by its second frame
The combining signal is accordingly solved the first baseband signal that branch after frame goes out present node M1 by processing module 32, and by described first
Baseband signal follow-up the first aerial unit 4a transmitted to the first stage unit 3a is connected to that continues of framing again.Need
Bright, the node M includes stage unit 3 and is connected to the aerial unit 4 of the stage unit 3 (for ease of description, this reality

And be combined and uplink after frame format framing by the 3rd frame processing module 42 by predetermined protocol the baseband signal
To the stage unit 3 of the node M.Preferably, the framing process includes setting the base band letter according to predetermined frame format
Number destination address.
Step S22, the first baseband signal that present node M1 uplink is come is come with next node M2 uplink
The second baseband signal be combined rear uplink.
The baseband signal that aerial unit 4b transmission comes is passed through described second by the stage unit 3b of the next node M2
Frame processing module 32 is transmitted to present node M1 after framing again.The stage unit 3a of present node M1 is up by aerial unit 4a
The baseband signal that the stage unit 3b uplink of baseband signal and the next node M2 that transmission comes passes through the second frame
After processing module 32 solves frame respectively, it is combined and framing again, the combining signal uplink that will then obtain is transmitted to ground list
Unit 2.Preferably, the solution frame process includes obtaining the signal according to predetermined frame format.
Step S23, will transmit the combining signals revivification for coming is radiofrequency signal, then enters the radiofrequency signal after the reduction
Row branch is simultaneously transmitted to corresponding base station 1 to complete up covering.
The surface units 2 by the first frame processing module 23 will transmit come the combining signal solution frame after, by the
One ifd module 22 carries out upconversion process and is converted to intermediate-freuqncy signal, then will by upconversion process by the first radio-frequency module 21
The intermediate-freuqncy signal is modulated to radiofrequency signal, and the radiofrequency signal branch that will then obtain simultaneously is entered using wave filter and/or amplifier
Corresponding base station 1 is gone upward to after row filtering and/or enhanced processing, to complete up covering.It should be noted that working as the ground
When unit 2 is communicated to connect with least two stage unit 3 respectively, the surface units 2 first will be single by described at least two classifications
At least two-way baseband signal and/or combining signal that the transmission of unit 3 comes pass through the first ifd module 22 and first again after being combined
Radio-frequency module 21 is converted to radiofrequency signal, and the radiofrequency signal branch that will then obtain simultaneously goes upward to corresponding base station 1, with completion
Row covering.
On this basis, can also be by string in the embodiment of the distributed communication covering method in the utility model embodiment
Connection and/or the cascade number for increasing the node M in parallel, expand communication overlay area.Now, the upward signal of each node M
Transmitting procedure and aforementioned process similarly.For example, when the next node M2 is also associated with another node (not shown),
Baseband signal that stage unit 3b in the next node M2 can carry out the aerial unit 4b transmission and it is described another
The baseband signal or combining signal that the transmission of stage unit 3 of node comes be combined after framing, the combining that will then obtain again
Signal transmission is to the present node M1 so that the stage unit 3a of the present node M1 will transmit combining signal and the institute for coming
State after the baseband signal that the aerial unit 3b transmission of present node M1 comes is combined and transmit to surface units 2 and be converted to radio frequency
Signal, the radiofrequency signal branch that will then be obtained by the surface units 2 simultaneously goes upward to corresponding base station 1, to complete up covering
Lid.It will be appreciated by those skilled in the art that in embodiment of the present utility model, when the target of the up radiofrequency signal of the multichannel
When the corresponding target device in address is same base station 1, above-mentioned shunt operation can be omitted.
In order to further improve the distributed communication covering method in the utility model embodiment emergent construction efficiency simultaneously
Expand communication overlay area, the combining signal also includes the feedback letter that the movable termination by carrying the antenna 45 sends
