Description
Technical field
The present invention relates to the field wireless communication technology field, be specifically related to a kind of micropower direct amplification machine that mobile telephone signal is amplified.
Background technology
The signal of present mobile operator covers and mainly contains two kinds: generally in the mode of outdoor employing base station, indoor be all generally to take microcell base station chamber minute engineering mode.
Continuous increase along with the density and height of City Building, and distribution apparatus and wiring are subject to the multiple condition restriction in all kinds of different building installation rooms, also have with property coordinate not smooth, with other many reasons such as insurmountable problem in a short time, the mobile telephone signal that all causes many operators in many buildings going wrong in various degree, most importantly very weak (signal of 3G frequency range is subjected to that frequency is high to signal and loss is large, problem is more serious), the user mobile phone signal difference; Or high-storey is subjected to frequent switching due to the overlapping covering of multiple base station signal and the mobile phone communication that causes often goes offline.The appearance of these a large amount of signal blind spots in city, have a strong impact on the considerable part mobile phone user and communicate by letter normally, causes a large amount of customer complaint problems, and each mobile operator is in the reply that actively seeks redress.
In recent years, adopting the mode that all kinds of micropower signal amplifying apparatus (miniature direct amplification machine) are installed to come this class of quick solution to complain progressively is used.
Prior art scheme one:
The domestic separate type micropower direct amplification machine (being commonly called as company of handset) of producing, the direct amplifying technique of the radio frequency that its principle mainly adopts.its major technique solution is: adopt the mobile telephone signal that donor antenna transmitting-receiving outdoor base station is installed in outdoor suitable position, introduce indoor with the radio frequency feed line of appropriate length again, and be connected on the micropower direct amplification machine that is placed in the covering point, after the amplification of suitably gain, directly or the feeder line by suitable length to being placed in indoor cover antenna, transmitting-receiving comes from the wireless signal of mobile phone, the wireless signal of base station direction and mobile phone direction has all obtained effective enhancing in this process, thereby comparatively effective realized the indoor mobile telephone signal of the weak signal area of body of wall due to stopping that is subjected to and covered.Aspect high-storey, the micropower signal amplifying apparatus is installed, optionally strengthen the outdoor base station signal of specific direction, suppress other bad signals, also can switch the frequent broken string problem that causes by solution high-storey signal to a certain degree.
Existing this antenna is relative simple with the technology of the equipment of the mode of the micropower direct amplification machine of main frame separate type arrangement, is easy to make the tandem product of containing whole mobile communication specification standards, and is with low cost.But its greatest problem is exactly the device structure complexity, needs to send the professional to on-site install, and just can guarantee the result of use that it is good.Because the design that is subjected to original know-why limitation and antenna and equipment limits, whole antennas can not be done and are in the same place with equipment, need to come the necessary Signal segregation degree of equipment work to work by external antenna.Its key problem in technology is the decay that the body of wall (various bricks, concrete etc.) that will reasonably utilize indoor each room produces signal, isolate the signal between donor antenna and cover antenna, usually the coupling amount therebetween that guarantees can also will not add 15dB outward over the maximum gain of direct amplification machine equipment, avoids forming the feedback self-excitation.When equipment and antenna are installed when mishandling, the feedback self-excitation that causes is in case formation will cause equipment effectively not work, also can produce simultaneously very large irregular radio frequency interference radiation, normal operation that also can the severe jamming base station in the time of in it falls into the base station signal frequency band, even stop up the BTS channel of this direction.To connect radio frequency feed line to indoor because be placed in outdoor donor antenna, can bring very large inconvenience under renovated building structure condition, and also have a lot of condition elements to take into account during because of erection unit, so while installing, need to send the installation personnel with good technique quality and experience to install to on-the-spot, to control, process and the effect of implementing is installed.But due to the place that may install very disperse and uncertainty very large, cause cost of labor and transport cost spending very large, simultaneously also there is certain security risk when the outdoor mounted donor antenna, and the entering indoor installation and also can bring very large puzzlement and inconvenience to the cellphone subscriber who is mounted equipment of unfamiliar personnel.And in city, many buildings do not allow and fix up an aerial wire, man of resident family does not allow wiring make the micropower direct amplification machine can't install at all.
Prior art scheme two:
now also has a kind of more advanced W-CDMA micropower ICS direct amplification machine equipment abroad, its whole antennas and main frame integrated design, import is at present also come into operation, what this equipment adopted is radio frequency frequency conversion Digital Signal Processing amplifying technique, (high-speed AD/DA+FPGA+DSP) mode comes the settling signal phase place to process in real time correction in signal process software radio high-speed digital signal processing after frequency reducing, allow and can keep in real time suitable phase relation between the radiofrequency signal of sending and receiving end, after processing like this, make the complete machine can be in the situation that isolation between transmitting and receiving antenna subtracts 15dB can also work, successful is effective.Owing to being integrated design, thereby this scheme can realize exempting from that the professional on-sites install goes the through engineering approaches concept, by the cellphone subscriber, is placed in voluntarily windowsill, can obtain good practical function.
This ICS direct amplification machine equipment adopts the complicated software and radio technique based on Digital Signal Processing, duplex channel all adopts the ICS know-why mode of high-speed AD/DA+FPGA+DSP to work, body is comparatively small and exquisite, can be installed voluntarily by the cellphone subscriber, and can obtain good practical function, can overcome to a great extent numerous disadvantages of the mode of foregoing split type micropower direct amplification machine.But due to its technical sophistication, equipment cost very high (being the several times of domestic separating apparatus), power consumption large (more than 10W), the one-time investment of operator is large, and return rate is low, is difficult to promote and can't uses in a large number.
Limitation due to signal processing technology complexity and market cost performance reason, only there is at present the practicality of W-CDMA technical specification standard to improve the product release, and not yet release perfect corresponding product on the standard specifications such as kind (as TD-SCDMA/CDMA2000) of other 3G frequency ranges, the technical specification standard that can deal with problems is limited in scope, and can't apply.
