Uplink Capacity Investigations of TDD/CDMA

摘要

1. TDD/CDMA has quite a poor uplink capacity, due to the serious BS-to-BS interference 2. Sectorisation, beam forming, MUD and frequency reuse can be employed for reducing the BS-to-BS interference, consequently for increasing the uplink capacity in TDD/COMA 3. Our recent work showed that frequency reuse factor 3 has the highest efficient capacity in terms of number of users per cell per carrier.
