A code division multiple access (CDMA) communication system in which cellular techniques are utilized in a wireless Private Branch Exchange (PBX) environment. A microcellular arrangement is defined in which a base station communicates user information signals using CDMA communication signals with subscriber terminals. A distributed antenna system is utilized in the system to provide multipath signals which facilitate signal diversity for enhanced system performance.
In a code division multiple access (CDMA) communication system in which system users communicate information signals with other system users through a base station using CDMA communication signals, said base station having an antenna system comprising: a plurality of spaced apart antennas; signal di
In a code division multiple access (CDMA) communication system in which system users communicate information signals with other system users through a base station using CDMA communication signals, said base station having an antenna system comprising: a plurality of spaced apart antennas; signal distribution means for coupling CDMA communication signals between a base station and said antennas; and delay means operatively coupled to said antennas and said signal distribution means for providing a predetermined delay in said CDMA communication signals coupled between said base station and said antennas.
