| Popis: | A new procedure is proposed for resolving multipaths for the wireless channel. This method uses antenna arrays at the base station to estimate the direction of arrival (DOA) of the multipaths. Beams are formed in the specific DOAs. Thus the significant paths can be separated from one another and then fed into the fingers of a RAKE type receiver. Each finger is adaptively adjusted for delay to achieve optimum combining. We show that such enhancement greatly improves the system performance. Results of preliminary simulation studies are also presented. |
