发明名称 Antenna system for a cellular telephone network
摘要 A cellular telephone system is described of the type wherein a plurality of contiguous cells, each having an assigned set of identification codes, are arranged with means for maintaining continuous communication with mobile telephones moving from cell to cell. The system allows multiple access by including means for assigning at least one of the in the assigned set of identification codes to more than one mobile telephone. A unique identification code is assigned to a mobile telephone located in the cell. A signal having a unique identification code is generated for identifying the mobile telephone. The signal is coupled to the zones. A combiner is also provided for combining signals from all of the zones in the cell. A receiver is coupled to the combiner for retrieving the signals having the code. According to another aspect of the invention, the signal coupled to the zones is delayed so that the transmission of the signal among the plurality of antenna sets is delayed by a preselected amount so as to reduce interference caused by successive reception of signals.
