Radio Network Arranging and Optimisation for UMTS comprehensively clarifies how you can dimension, prepare and optimise UMTS (Common Mobile Telecommunications System) networks. It introduces the Qualities on the spread spectrum technique and delivers a normal overview in the physical layer of UTRA FDD. The radio network preparing approach for WCDMA is Evidently offered and specific information on tips on how to dimension, system and rollout a 3G network, both of those theoretically and practically is delivered.
This information analyzes general performance of HS-SFN for macro cell state of affairs beneath diverse channels with distinctive type of schedulers by means of in depth procedure stage simulations and indicates that HS- SFN can maximize throughput for UEs in softer handover space from 40% to 80% without lowering the overall efficiency.
On the other hand, considering the fact that HSPA network end customers execute far more downloads than uploads, HSDPA speeds are In a natural way Considerably better than HSUPA. website This is certainly also the reason why HSDPA techniques are increasingly being deployed way forward of their HSUPA counterparts.
数字信号相乘，由于伪随机码速率快，扩展了传输带宽（伪随机码带宽远大于信号带宽，扩展信号频谱），在接收端，用相同的伪随机码序列
