Abstract: Distributed wireless communication system (DWCS) is built with distributed antennas, distributed transport and distributed processing. An arbitrary set of antennas can constitute a virtual cell for a certain mobile user. Code division multiple access(CDMA) and maximum ratio combining (MRC) were employed by DWCS for the system construction. Considering inter-user interferend to a certain user, inference users are divided into 3 groups: the users with the same antenna set; the users with a completely different antenna set; and the users with sharing part of antenna set. Another two works we have done were: evaluations of reverse link capacity by calculating the other-cell interference factor f_d; and comparisons of DWCS with traditional single-antenna and multi-antenna cellular systems under condition of the same antenna density. The analysis shows that the reverse link capacity greatly increases when used in DWCS.
