In multicarrier code-division multiple access systems the linear distortion introduced by the channel causes a perturbation in the received user codes that produces multiple access interference. This paper introduces two new techniques to combat this distortion that are based on subspace decomposition. The first one consists of obtaining an approximation of the received desired user code to improve...
The paper investigates the problem of manoeuvring target tracking using angular measurements. The target dynamics is modelled by multiple switching models, while the measurements are collected asynchronously from possibly multiple moving platforms. The contribution of the paper is twofold. First a theoretical lower bound of the performance error is derived and analysed. Second, three tracking algorithms...
