Multiple antennas system for multiaccess capacity enhancement with flexible antenna locations

The scheme proposed here is an alternative of smart antenna systems, with flexible antenna locations and easy capacity expansion. Here, unlike cell splitting, the only purpose of building a base station is for radio coverage, and capacity enlargement is done by multiple antennas. In this paper, after analyzing its capacity, we put forward a transceiver method (group transmission) for multiple antenna system to approach the great capacity enhancement, without any multi-user coding/decoding technique and excessive bandwidth. Performance evaluation shows that this scheme approaches the capacity well and is quite suitable for PCS
