A SECRET WEAPON FOR IMS (IP MULTIMEDIA SUBSYSTEM)

HSDPA and HSUPA incorporate new abilities to your 3G UMTS (Universal Mobile Telecommunication Method) networks for FDD and TDD deployments. The main focus of HSPA (HSDPA and HSUPA) is higher little bit rates and decreased latencies. As Section of 3GPP release 5, HSDPA introduces a brand new large-speed downlink channel shared among multiple custome

复杂度 ：算法的复杂度会影响设备的实现成本和功耗，因此在实际应用中需要权衡性能和成本。开环功率控制 ： 开环功率控制是基于接收信号强度的预测进行的，它不需要反馈信息。在移动终端接入网络时，会根据信号的衰落特性预先设定发射功率。开环控制主�
