Description
Technical field
The present invention relates to wireless communication field, comprise space and land, move and fixing wireless communication field.
Background technology
Existing cordless communication network exists the four problems that can't resolve for a long time with prior art and equipment, and this four problems is:
1, because the restriction of geographical position (ocean, desert and hills etc.), environmental protection and right-safeguarding (commercial and residential quarter and historic reservation etc.) and the condition of building a station (electric power, iron tower, transmission, fund etc.) can't solve communication coverage hole problem by newly-built station;
2, because wireless terminal device is subjected to restrictions such as little antenna size, battery capacity, transmitting power, terminal (can make mobile phone or wireless Internet card etc. to land mobile communication network, to satellite communication can be transponder) (land mobile communication network is called the base station to main website, to satellite communication can be ground station) transmission link be weak link, its performance is well below main website to the link of terminal performance, promptly there is uplink and downlink link imbalance problem, and weak link has determined the covering and the communication quality of network, becomes the bottleneck of realizing the high performance network system;
3, the number of present all kinds of main website and terminal equipment increases severely day by day, wireless communication frequency resource anxiety, use spectral frequencies more and more higher, propagation characteristic worse and worse, the main website spacing is more and more nearer, it is serious day by day that Intranet and competition net and other disturb the frequency that produces to pollute, and the main website snr of received signal is descended, and has a strong impact on communication covering, communication quality and power system capacity;
4, CDMA(Code Division Multiple Access, code division multiple access) system of standard exists the self-interference between code channel, produce cell breath, add all kinds of air interference and the soft handover that needs 30% fixed channel expense, often make system operating capacity not reach 60% of theoretical capacity.
Above-mentioned four problems causes wide coverage distance deficiency, covers that the signal penetration rate is low deeply, degradation problem under communication quality variation, frequency and power system capacity and utilization rate of equipment and installations reduction, rate of return on investment and the user satisfaction.At an above difficult problem, what adopt at present all is conventional art means and the equipment that falls behind, and analogy increases new main website equipment, increases the carrier number of main website, sets up tower and puts equipment and repeater equipment and microcellulor indoor distributed system equipment etc. are installed.
Adopt the shortcoming of conventional art means and equipment as follows:
1, the receiver of existing all devices does not all have, very precipitous with the conventional art characteristic that also can not accept filter, it is little to insert minimum, the wide passband passband fluctuation of loss, squareness factor is near 1 radio frequency band filter, the interference of filtering passband outer (stopband) effectively, reach these interference of reduction and enter the Intermodulation Interference that receiver further causes, raised system's back noise;
2, above-mentioned all devices amplifies simultaneously to signal and the noise that receives, be that noise adds up receiving on the link, rather than weaken, the result be received signal quality worse and worse;
3, the low noise amplifier of the receiver radio frequency front end of above-mentioned all devices is worked at normal temperatures, because the electronics Brownian movement produces thermal noise, amplifier has amplified the noise that self produces, and has raised system's back noise, makes signal-to-noise ratio degradation; Influence communication covering seriously and quality and capacity;
4, communication covering and poor quality's place, the zone of the network planning often, main website layout unreasonable (, sub-district too high switch frequent or covering and frequency planning unreasonable etc.), pilot pollution and all kinds of serious interference such as land mobile base station closeness, increase main website, frequency configuration and equipment disposition in these zones, great amount of investment but brings interference and frequency to pollute further seriously often, system and maintenance costs increase, and resource utilizations such as frequency and equipment further reduce; In fact, the most of interference source of network and the source of trouble come from that tower is put, repeater and indoor distributed system, severe contamination network environment;
5, because factors such as available resources, internal and external interference and business demand quantitative changeization are not self controllable, be the passive engineering of mending the fold after the sheep is lost forever so solve problem with above-mentioned method and technology.
In sum, use existing traditional technological means and equipment fundamentally not solve: to remove outer the interference and Intermodulation Interference; Reduction system self back noise; Improve problem effectively to the gain and the sensitivity of useful signal.
At the problems referred to above, the applicant has proposed a thinking and a technical scheme of overlapping the brand-new network planning, construction, optimization and O﹠M: the superconductor technology of utilizing that installs a kind of applicant's independent development at wireless main website front end additional is improved the superconduction chain-circuit system of wireless main website received signal (SuperConductor Link System, SCLS; Trade name Beyond Link, BL is hereinafter to be referred as BL).BL can overcome the shortcoming of prior art and equipment from root, network performance is had revolutionaryly improve:
1, high-Q filter brings extremely strong antijamming capability.BL adopts high-Q filter to bring extremely strong antijamming capability.At 825-835MHz, adopt high temperature superconducting materia to make radio frequency band filter such as, passband, its insert loss almost nil (＜0.02dB), and traditional cavity body filter inserts loss usually 1dB; Squareness factor is near 1, and quality factor (Q value) are 100,000 the order of magnitude, is 20 times of traditional cavity body filter Q value; Stopband has the above steep attenuation characteristics of 40dB/MHz, the attenuation characteristic about 3dB/MHz and traditional cavity body filter stopband is only had an appointment, and difference is very big.Its characteristic is brought extremely strong antijamming capability and is reduced Intermodulation Interference effectively;
2, under the ultra-low temperature surroundings, low noise amplifier (Low-noise amplifier is called for short LNA) reduces system's back noise effectively, improves system gain.The LNA of BL is operated in 77K(-196.15 ℃) about ultra-low temperature surroundings under, suppressed LNA itself effectively because the thermal noise that Brownian movement produces, reduced system's back noise, LNA brings the raising of gain more to useful signal simultaneously, at normal temperatures, the best noise factor of LNA and under ultra-low temperature surroundings, can reach about 0.2-0.3 dB about 0.6dB.
In a word, BL has high anti-band to be disturbed outward and reduces the Intermodulation Interference ability, can reduce system's back noise effectively and useful signal is brought gain simultaneously, thereby solve the problem that prior art and equipment can't resolve, and improves wireless network performance greatly.
