Software testing is a major approach to software quality assurance, but it is relatively neglected in universities' computing curricula. For students majoring in computer science or software engineering, several basic testing methods need to be taught. These testing methods generate test cases based on either specifications or program code. When introducing the testing methods based on program code, it is not easy to let the students experience automated test case generation due to the lack of supporting tools and limited teaching hours. In this paper we report our experience in teaching this topic with limited resources. The evaluation result indicates …

Although generation of correlated Rayleigh fading envelopes has been intensively considered in the literature, all conventional methods have their own shortcomings, which seriously impede their applicability. In this paper, a very general, straightforward algorithm for the generation of an arbitrary number of Rayleigh envelopes with any desired, equal or unequal power, in wireless channels either with or without Doppler frequency shifts, is proposed. The proposed algorithm can be applied to the case of spatial correlation, such as with multiple antennas in Multiple Input Multiple Output (MIMO) systems, or spectral correlation between the random processes like in Orthogonal Frequency Division …
