Hot-beam traffic relief for cellular SBF multi-beam array antenna CDMA systems

We analyze the performance of the beam reassignment (BR) method, which provides a load sharing to mitigate the hot-spot beam, named hot-beam, of switched beamforming (SBF) array antenna CDMA systems. As a result, it is shown that the feasible range of the traffic load ratio of the hot-beam to the li...

Zusammenfassung:	We analyze the performance of the beam reassignment (BR) method, which provides a load sharing to mitigate the hot-spot beam, named hot-beam, of switched beamforming (SBF) array antenna CDMA systems. As a result, it is shown that the feasible range of the traffic load ratio of the hot-beam to the lightly loaded beam, where the total blocking probability of the cell is below 1%, is increased at least 9.49%, 15.19%, and 6.72% when the main beamwidth is 60/spl deg/, 30/spl deg/, and 15/spl deg/, respectively.
