101, calculation element is according to preset ratio, is edge Insertion Loss band and typical Insertion Loss band by the frequency band division of passage in mixer.
Wherein, in the system of described typical Insertion Loss Dai Weihe road, performance reaches the frequency band of preset standard, close performance in the system of road described in described edge Insertion Loss band and do not reach the frequency band of preset standard, described conjunction road system is the communication system that mixer closes road, described conjunction paths and described conjunction road system one_to_one corresponding, described mixer at least comprises Liang Gehe road system.
102, calculation element calculates the Insertion Loss value of described typical Insertion Loss band, and calculates the Insertion Loss value of described edge Insertion Loss band according to the Insertion Loss value of described typical Insertion Loss band.
103, the Insertion Loss value of the Insertion Loss value of described typical Insertion Loss band and described edge Insertion Loss band is defined as the Insertion Loss value of described mixer by calculation element.
In the embodiment of the present invention, described edge Insertion Loss band can comprise left hand edge Insertion Loss band and right hand edge Insertion Loss band, and described left hand edge Insertion Loss band and described right hand edge Insertion Loss band are positioned at the two ends of described typical Insertion Loss band; Then the Insertion Loss value of described edge Insertion Loss band comprises the Insertion Loss value of left hand edge Insertion Loss band and the Insertion Loss value of right hand edge Insertion Loss band.The conjunction road system of described mixer can also close road system for adjacent frequency.
First according to preset ratio in the present invention, be edge Insertion Loss band and typical Insertion Loss band by closing in paths the frequency band division being used for signal transmission, in the system of typical case Insertion Loss Dai Weihe road, performance reaches the frequency band of preset standard, close performance in the system of road described in edge Insertion Loss band and do not reach the frequency band of preset standard, but namely may be used for transmitting data have certain influence frequency band to systematic function; Then the Insertion Loss value of typical Insertion Loss band and the Insertion Loss value of edge Insertion Loss band is calculated respectively; Again according to the Insertion Loss value of the Insertion Loss value of typical Insertion Loss band and the Insertion Loss value determination mixer of edge Insertion Loss band.So, when determining the insertion loss of each passage in mixer, calculate the Insertion Loss of edge Insertion Loss band and typical Insertion Loss band respectively, the insertion loss that calculates is enable to close within the scope of the insertion loss that road entire system performance loss can tolerate, and draw the insertion loss value that the edge insertion loss value of closing paths draws in prior art, so when mixer isolation is certain, method of the present invention will reduce the isolation bandwidth of mixer, and then the frequency resource that reduction isolation bandwidth takies, reduce frequency resource waste.
Further embodiment of this invention provides a kind of computational methods of mixer insertion loss, for calculation element, for computer, mixer is for adjacent frequency mixer, the system of closing road is needed to be that the first conjunction road system and second closes road system, the first passage of the corresponding mixer of the first conjunction road system, the second channel of the corresponding mixer of the second conjunction road system, as shown in Figure 2, described method comprises:
201, the frequency band of the frequency band of first passage and second channel is divided into edge Insertion Loss band and typical Insertion Loss band according to preset ratio by calculation element respectively.
Wherein, preset ratio can set according to the concrete condition of system, and in the system of typical Insertion Loss Dai Weihe road, performance reaches the frequency band of preset standard, closes performance in the system of road and do not reach the frequency band of preset standard described in described edge Insertion Loss band.
It should be noted that, edge Insertion Loss band can comprise left hand edge Insertion Loss band and right hand edge Insertion Loss band, and left hand edge Insertion Loss band and right hand edge Insertion Loss band are positioned at the two ends of typical Insertion Loss band.When edge Insertion Loss band comprises left hand edge Insertion Loss band and right hand edge Insertion Loss band, preset ratio directly can provide the ratio of left hand edge Insertion Loss band, typical Insertion Loss band and right hand edge Insertion Loss band.
202, calculation element calculates the Insertion Loss value of typical Insertion Loss band in first passage.
Wherein, the method calculating the Insertion Loss value of typical Insertion Loss band can for calculating the method for Insertion Loss in prior art.Such as, calculate the method for the Insertion Loss value of typical Insertion Loss band in first passage, first can close road system uplink sensitivity budget according to first and determine that upstream sensitivity allows the Insertion Loss value of falling quick value correspondence; Then determine that descending power allows the Insertion Loss value that pad value is corresponding according to the first system descending power link budget; Minimum value among using both is as the Insertion Loss closing road system respective channel.

It should be noted that, in LTE communication system, system bandwidth can be divided into Resource Block one by one, the sub-fraction Resource Block Insertion Loss closing road system edges transition band can higher than the Insertion Loss of passband portion, but in LTE system, edge height Insertion Loss only affects the performance of its place Resource Block, little on the impact of entire system performance, and, LTE system carries out assessment and the scheduling of signal quality in units of less frequency range, and the time-frequency characteristic change direction of mixer median filter transition band is consistent, it is milder that this makes channel characteristics change, now close road system and be aided with the adaptive scheduling matched again, just can make up the performance inconsistency that the larger Insertion Loss of Insertion Loss band involutory road, edge entire system is brought, impact is reduced to minimum.In sum, closing paths edge Insertion Loss band can signal transport tape, and the computational process of its Insertion Loss realizes according to step 203-step 205.
210, the Insertion Loss value of first passage typical case Insertion Loss band, the Insertion Loss value of first passage edge Insertion Loss band are defined as the Insertion Loss value of mixer first passage by calculation element, the Insertion Loss value of second channel typical case Insertion Loss band and the Insertion Loss value of second channel edge Insertion Loss band are defined as the Insertion Loss value of mixer second channel.
Wherein, the Insertion Loss value of the Insertion Loss value of the first passage calculated typical case Insertion Loss band, first passage edge Insertion Loss band, the Insertion Loss value of second channel typical case Insertion Loss band and the Insertion Loss value of second channel edge Insertion Loss band are directly defined as the Insertion Loss value of each passage of mixer by calculation element respectively.After the Insertion Loss determining mixer and isolation, the isolation bandwidth of mixer can be calculated.
First according to preset ratio in the present invention, be edge Insertion Loss band and typical Insertion Loss band by closing in paths the frequency band division being used for signal transmission, in the system of typical case Insertion Loss Dai Weihe road, performance reaches the frequency band of preset standard, close performance in the system of road described in edge Insertion Loss band and do not reach the frequency band of preset standard, but namely may be used for transmitting data have certain influence frequency band to systematic function; Then the Insertion Loss value of typical Insertion Loss band and the Insertion Loss value of edge Insertion Loss band is calculated respectively; Again according to the Insertion Loss value of the Insertion Loss value of typical Insertion Loss band and the Insertion Loss value determination mixer of edge Insertion Loss band.So, when determining the insertion loss of each passage in mixer, calculate the Insertion Loss of edge Insertion Loss band and typical Insertion Loss band respectively, the insertion loss that calculates is enable to close within the scope of the insertion loss that road entire system performance loss can tolerate, and draw the insertion loss value that the edge insertion loss value of closing paths draws in prior art, so when mixer isolation is certain, method of the present invention will reduce the isolation bandwidth of mixer, and then the frequency resource that reduction isolation bandwidth takies, reduce frequency resource waste.
