摘要： A monitoring apparatus, a wireless communication system, a failure-cause distinguishing method, and a non-transitory computer readable medium storing a program that enable a user to appropriately cope with fading are provided. A monitoring apparatus (1) includes an acquisition unit (12) and a distinguishing unit (14). The acquisition unit (12) acquires history data which is generated in one or more wireless communication apparatuses and which indicates at least information related to the time at which failures have occurred in each predetermined time period and related to a received signal level therein. The distinguishing unit (14) distinguishes the type of fading that has occurred in the wireless lines related to the wireless communication apparatuses based on the history data.

摘要： A device receives fading channel conditions to utilize for simulating behavior of multiple mobile devices in a mobile network, and at least one of the fading channel conditions for at least one of the multiple mobile devices is different than at least another one of the fading channel conditions for at least another one of the multiple mobile devices. The device generates channel realizations based on the fading channel conditions, and the channel realizations include time-discrete and frequency-discrete random channel coefficients. The device generates a test channel based on the generated channel realizations, and provides the test channel to a receiver device of the mobile network. The test channel causes the receiver device to perform functions associated with processing an actual channel.

摘要： Natural radio environments are virtualized to test radio devices. In one example, this is done by extracting signals and messages recorded in the field and injecting them in the operation of a protocol tester. In another example, the radio environment is reproduced by generating channel impulse responses in a ray-tracer, then interpolating them in a channel emulator and supporting the interpolation by means of post-processing. In another example, the radio environment is recorded using a mobile terminal in the field. In another example, natural radio environments are produced by reconstructing realistic cell loads and, as a consequence, intra-cell interference for a given device under test.

摘要： In one embodiment, a cellular wireless communications network, such as a large-scale antenna system (LSAS) network, having multiple base stations is logically divided into overlapping, virtual, truncated networks, where each base station functions as the master of a different truncated network, and each truncated network also has one or more base stations that function as slaves to that master base station. Each master base station generates estimated slow-fading coefficients and a slow-fading post-coding (SFP) vector based only on the wireless units current located within its truncated network. In particular, to generate the SFP vector, the master collects estimated slow-fading coefficients and estimated uplink data symbols from its slaves. The master uses the SFP vector to update its own estimated uplink data symbols for the wireless units currently located within its own cell.
