In this paper, we investigate the performance of the Code Division Duplex (CDD) system using the interference rejection codes, which exhibit zero correlation values on the relative delay-induced code offsets and can be applied to mitigate the mutual interference between the uplink and downlink. Specifically, we propose to employ loosely synchronous codes to effectively combat the interference through...
We address the severe interference condition with unity frequency re-use factor in each cell and propose a novel distributed receiver for reliable detection of the uncoded data transmitted in multi-user multi-cell multiple input, multiple output (MIMO) systems. The new algorithm employs distributed probabilistic data association (PDA) with turbo base-station (BS) cooperations (PDA-TB). From a Bayesian...
A force acquisition system for digital impact tester was investigated, in which structural design of bar-shaped elastic element, circuit design as well as static analysis were involved. Based on analysis of international requirements on the detection precision of digital impact tester, information concerning the precision of sensor parameters, sensors and adhesive was collected, and adhesion sites...
