Embodiment Construction
[0074] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.
[0075] Such as figure 1 As shown, what this solution needs to solve is to address the appeal problem. For the physical port of each channel emulator, due to the individual differences of components, the possible loss of components during long-term use, in order to be able to perform channel simulation each time It can achieve the best equipment status and effectively increase the service life of the entire channel emulator and reduce the failure rate. Before each channel simulation test, the system adaptively configures the connection mode of the topology that the model needs to use.
[0076] Integrate the historical data of attributes related to port performance, use the neural network to evaluate the correlation between attributes, and f...

The invention discloses a method for realizing an adaptive topology structure based on a channel emulator, which includes: pre-evaluation, according to the port temperature deviation ratio of the current device from the start-up to the preparation test and the port calibration data deviation ratio after automatic calibration, Obtain pre-evaluation; historical data evaluation, according to the historical unit temperature average deviation ratio and total time deviation ratio, obtain the historical data evaluation of the device port after leaving the factory; failure rate; obtain the pre-evaluation by using the neural network for forward and reverse iterations on the sample set Weight value and weight value of historical data evaluation; according to pre-evaluation, historical data evaluation, failure rate and pre-evaluation, historical data evaluation weight value, single-port performance evaluation is obtained; by obtaining the evaluation performance of each port, the evaluation of each port Evaluate the performance for performance sorting, and complete the adaptive configuration of the connection mode of the topology according to the sorting sequence. Through the present invention, the balance of the utilization rate of each port is realized.
Description
technical field [0001] The invention relates to the communication field, in particular to a method for realizing an adaptive topology structure based on a channel emulator. Background technique [0002] The channel emulator is a software and hardware integrated device for MIMO wireless channel simulation. It is connected to the channel emulator through the base station terminal antenna to simulate the transmission path of the channel in space. In actual use, due to different model requirements and different device connection methods, there will be differences in performance, stability, and service life of the ports used. [0003] The traditional way of port selection in the topology structure is to use a combination of default sorting and user-defined, but here, due to human usage habits, they are all selected from top to bottom and from left to right. This habit will lead to unbalanced port usage, which will cause some ports or boards to degrade performance due to excessiv...
