Summary: | In this paper, we consider fixed wireless access (FWA) systems with antenna arrays. We consider both the downlink and the uplink. Multiple antennas are used at the transmitters, as well as the receivers. We demonstrate that with antenna arrays, the user capacity of a system can be dramatically increased, allowing multiple users to use the same narrowband spectrum simultaneously. In general, it may be difficult to determine the optimal transmission vectors. We consider a simple algorithm that often yields desirable solutions. We also consider the special case of co-located users. The communication system then reduces to a point-to-point communication link where the optimal transmission vectors can be determined under some conditions. |
