Here I write short notes on how to test open loop and close loop testing in lte and what idea behind it. In open loop no any data send back and in closed loop all relevant data available to both side lets check in some detail. Open and close loop testing in LTE: Open loop … Read more
There are a number of relatively independent base band processing units and carrier processing units in the system. The working frequency carrier of each carrier processing unit is fixed, the service information of each communication path is processed by fixed base band unit, and then the processed information is transferred to carrier units of different … Read more
Here I write about antenna pattern, Front-to-rear Ratio and Upper Side Lobe Suppression in antenna. Antenna Pattern The pattern is the electromagnetic field of antenna radiation distributed by coordinate along fixed distance. If the pattern is represented by radiation field strength, it is called field strength pattern. If the pattern is represented by power density, … Read more
