| Abstract(in English) | In this paper, we propose the decision feedback radial basis function (DFRBF) detector using the RBF network and the linear minimum mean-square error (MMSE) detector, which can update the RBF network's parameters with the blind adaptive technique. Moreover, the MMSE detector estimates some user's signals which cause the near-far problem, and the RBF network of the DFRBF detector estimates the others which have weak received amplitude. As a result, the DFRBF detector can reduce the computational complexity, and it can update the parameters without training sequences. The simulation results show the proposed DFRBF detector outperforms the matched filter, the MMSE detector, and the decorrelating detector in asynchronous DS/CDMA communications. |
