Over the air testing of multiple antenna systems has attracted great attention in recent years. The research and standardization work have been focused on evaluating user equipment (UE) in two dimension (2D) radio propagation channel models. This paper proposes two future direction of over the air testing: 1) performance evaluation of WiFi devices under realistic propagation scenarios and 2) 3D radio...
In order to track the dynamic information of the tested system, get the analysis of coverage and time performance, It is critical to optimize the test technique efficiency. With the help of instrumentation to identify program block, this paper proposed an algorithm IPFG for constructing program flow graph, which is based on analyzing instrumentation information derived from program block This approach...
A test suit need be reused in regressing test, which may contain repetitive and redundant test cases. To decrease the cost of maintaining the test suite and executing test cases in regression testing, according to selective regression testing, we select the test cases that can test part of changes, and then do the reduction for these selected test cases. Based on the requirements of static path coverage...
In this paper, we propose a latent factor regression model, in which priors are assigned to both the latent regression vector and the error term, by using reproducing kernels. The resulting regression function follows a stochastic process known as a student process. The model is attractive because its implementation is based on a tractable posterior predictive distribution and a simple expectation-maximization...
