Abstract(in English) | This paper presents an improvement method of convergence of multi-access interference suppression algorithm for DS/CDMA communications over multipath channels. The convergence to the optimal filter coefficients cannot be ensured for the MOE algorithm, which is one of interference suppression filters. In order to solve the problem, Ishikawa et al. proposed the MSIR algorithm, which converges the optimal filter coefficients with the desired signal. However, the convergence of the MSIR algorithm is influenced by the desired user's estimate signal. We propose an interference suppression algorithm using variable step law, which changes the MOE algorithm to the MSIR algorithm due to reliability of the desired user's estimated signal. Simulation results show the proposed algorithm has better performance than conventional algorithms. |
