Description
Technical field
The present invention relates to the radio frequency reception technique, particularly relate to a kind of radiofrequency signal receiving element and method.
Background technology
In third generation communication system, because a large amount of multi-carrier receivers that use make the structure of base station receiver simplify greatly, veneer quantity also significantly reduces, and the receiver corresponding with sector only has a veneer.In this case, the requirement of the reliability index of veneer is also improved greatly, receiver veneer signal that will cause a sector that breaks down receives at a standstill, this shows, the reliability of veneer is extremely important, so, must take the scheme that the receiver veneer is backed up.
Generally speaking, the scheme of N+1 backup is adopted in the base station, if the base station covers N sector, N+1 receiver is set so, wherein N receiver is the work receiver, receive the signal of N sector respectively, surplus next receiver is made the backup receiver, takes over the signal that this work receiver receives corresponding sector when breaking down for the work receiver.For example, for the WCDMA base station of one three sector two carrier frequency, use four two carrier receivers, each receiver comprises a veneer, two receive paths are arranged on the veneer of each receiver: main collection passage and diversity passage are respectively applied for main collection signal and the diversity signal of handling corresponding sector.In four receivers three respectively to three sectors that should the base station covered, and reserve a receiver that is in idle condition, as backup.When a receiver breaks down, by the radiofrequency signal Switching Module, the main collection signal and the diversity signal of the corresponding sector of fault receiver are switched to respectively on the main collection passage and diversity passage that backs up receiver, support the work of fault receiver by the backup receiver.
Fig. 1 is the schematic diagram of the radiofrequency signal receiving element structure of prior art, is example with the base station of three sectors, and this radiofrequency signal receiving element comprises four receivers and radiofrequency signal Switching Module 100.As can be seen from the figure, receiver 1 is corresponding with sector 1, and receiver 2 is corresponding with sector 2, and receiver 3 is corresponding with sector 3, and the backup receiver under normal circumstances is in idle state, has only when the receiver corresponding with the sector breaks down and just starts working.
The main collection antenna of three sectors and diversity antenna collect between passage and the diversity passage with the master of corresponding receiver and are connected by radiofrequency signal Switching Module 100, this radiofrequency signal Switching Module 100 comprises 18 contacts, be expressed as contact 1 respectively to contact 9, and contact 11 is to contact 19.
Contact 3, contact 6 and contact 9 link together, and these three contacts all are connected with the main collection passage of backup receiver; Contact 13, contact 16 and contact 19 link together, and these three contacts all are connected with the diversity passage of backup receiver.
Contact 1 is to be connected with contact 2 or contact 3; Contact 4 can be connected with contact 5 or contact 6; Contact 7 can be connected with contact 8 or contact 9; Contact 11 can be connected with contact 12 or contact 13; Contact 14 can be connected with contact 15 or contact 16; Contact 17 can be connected with contact 18 or contact 19.
Under normal condition, the contact 1 of radiofrequency signal Switching Module is connected with contact 2, and contact 4 is connected with contact 5, and contact 7 is connected with contact 8, and contact 11 is connected with contact 12, and contact 14 is connected with contact 15, and contact 17 is connected with contact 18.Like this, the main collection passage of receiver 1 and diversity passage receive respectively from the main collection antenna of sector 1 and the signal of diversity antenna; The main collection passage of receiver 2 and diversity passage receive respectively from the main collection antenna of sector 2 and the signal of diversity antenna; The main collection passage of receiver 3 and diversity passage receive respectively from the main collection antenna of sector 3 and the signal of diversity antenna.In this case, the main collection signal of sector 1 and diversity signal enter the main collection passage and the diversity passage of receiver 1 respectively; The main collection signal of sector 2 and diversity signal enter the main collection passage and the diversity passage of receiver 2 respectively; The main collection signal of sector 3 and diversity signal enter the main collection passage and the diversity passage of receiver 3 respectively.
When receiver 1 broke down, the contact 1 of radiofrequency signal Switching Module changed into contact 3 and being connected, and contact 11 changes into contact 13 and being connected, and the annexation of all the other contacts is constant.Like this, the main collection signal of sector 1 and diversity signal enter the main collection passage and the diversity passage of backup receiver respectively.Like this, the main collection signal of the sector 1 of fault receiver 1 correspondence and diversity signal can be received by the main collection passage and the diversity passage of backup receiver, still can keep normal work.
When receiver 2 broke down, the contact 4 of radiofrequency signal Switching Module changed into contact 6 and being connected, and contact 14 changes into contact 16 and being connected, and the annexation of all the other contacts is constant.Like this, the main collection signal of sector 2 and diversity signal enter the main collection passage and the diversity passage of backup receiver respectively.Like this, the main collection signal of the sector 2 of fault receiver 2 correspondences and diversity signal can be received by the main collection passage and the diversity passage of backup receiver, still can keep normal work.
When receiver 3 broke down, the contact 7 of radiofrequency signal Switching Module changed into contact 9 and being connected, and contact 17 changes into contact 19 and being connected, and the annexation of all the other contacts is constant.Like this, the main collection signal of sector 3 and diversity signal enter the main collection passage and the diversity passage of backup receiver respectively.Like this, the main collection signal of the sector 3 of fault receiver 3 correspondences and diversity signal can be received by the main collection passage and the diversity passage of backup receiver, still can keep normal work.
The shortcoming of this scheme need to be veneer idle under the normal condition to support backup, realizes that cost is higher.Under the situation not high in receiver single board default rate, that reliability is medium, configuration is with the configuration backup veneer is all not satisfactory, the configuration backup veneer will cause higher cost and lower veneer utilance, and configuration backup veneer not, because the veneer reliability is general, so will influence the base station whole reliability.
