Description
Technical field
The present invention relates to communication technical field, particularly relate to a kind of non-boundary network channel environmental simulation method and
System.
Background technology
Wireless channel is to a kind of Vivid analogy of path between transmitting terminal and receiving terminal in radio communication.Nothing
In line channel, the propagation of electric wave is not single-pathway, but the synthesis of numerous echos in many paths.By
Different by the distance in each path in electric wave, thus the echo that each path is come is different for the time of advent, also
The time delay being exactly each signal is different.When transmitting terminal sends a pulse signal the narrowest, mobile station receives
Signal is made up of the pulse of many different delay, is referred to as delay spread.
Due to the mobility of mobile station in mobile communication, as previously mentioned, wireless channel also have how general
Strangle effect.In mobile communications, when mobile station shifts to base station, frequency uprises, during away from base station, and frequency
Step-down.Therefore arriving the mulitpath of receiving terminal in addition to time of advent difference, frequency is the most variant, is formed
Frequency is expanded.
The echo come due to each path is different for the time of advent, and frequency is different, and phase place is also the most different.Different
Multiple signals of phase place, at receiving terminal superposition, strengthen (direction is identical) because of superposition signal sometimes, and superposition is led sometimes
Cause signal weakening (in opposite direction).So, the amplitude receiving signal will drastically change, and i.e. create rapid fading.
This decline is to be caused by multiple path signal superposition, so referred to as multipath fading.
Additionally, reception signal is in addition to rapid fading occurs in instantaneous value, median of field strength (meansigma methods) also there will be
Slowly varying.Mainly caused by the change of zone locations and meteorological condition change, so that the folding of electric wave
Penetrating propagation to change over and change, the time delay of the signal that multipath transmisstion arrives fixed reception point changes therewith.
This signal intensity caused by shadow effect and meteorological reason, referred to as slow fading.
The radio channel characteristic more than referred to, including multipath transmisstion, fading characteristic and Doppler effect etc.,
It it is only the wireless channel of point-to-point.In cellular mobile telecommunications, the signal that terminal sends is except by service base
Stand outside reception, also received by multiple neighbor base stations adjacent with serving BS, constitute up to neighbor base station

Number configuration brings great difficulty.Generally wireless base system, before batch commercialization, is difficult to predict it at net
Systematic function under network environment；Even if base station system has passed through laboratory system test.The most commercial whole
End listing also faced similar problem in the past.
The system test environment built in laboratory the most only supports function and the performance verification of point-to-point, i.e.
Only possess wireless channel simulation ability, do not possess radio network information channel analog capability.Exactly because also laboratory
System test cannot portray the channel characteristics in actual wireless network environment, generally criticizes in base station system or terminal
Before amount commercialization, need to build certain scale commercialization pilot office, deposit fully to expose in base station system or terminal
Problem.Scale commercialization pilot office needs to put into a huge sum of money, and needs considerably long construction and open-minded
Time, therefore become the extravagant hope before base station system or end product mass marketed.
In order to promote the coverage of system test, it is proposed that one builds radio network information channel simulation at laboratory
The method and system of environment, tests and performance verification for base station system or end product.But the method mould
The network size intended is limited to hardware processing capability and interface number, it is difficult to Large Scale Analog Networks channel circumstance.
