The chapter focuses on the transition of some RRM capabilities including the packet scheduler into NodeB. The adjustments in RRM capabilities on the network nodes resulted in more modifications of HSDPA air interface such as introduction of better‐buy modulation and coding strategies, and modification in the MAC protocol architecture for enabling the rapid scheduling in the BTS.
DSSS is Direct Sequence Spread Spectrum Procedure that's a spread spectrum system during which the data being transmitted is encoded working with spreading code and been given and after that decoded using the identical code.
It organizes know-how and company procedures into levels described by activities occurring, and it outlines how an enterprise can setup an interface to communicate amid these levels.

CDMA technological innovation enables multiple buyers to share a similar frequency band concurrently by assigning a novel code (or channelization code) to each person. This code distinguishes a person person's data from A further's on the exact same frequency.
是利用电磁波的反射特性来探测目标。雷达发射机产生特定频率、波形的电磁波，经由天线向空间定向辐射，形成具有一定方向性的波束。当波束遇到目标物体时，电磁波会在目标表面发生反射，其中部分反射波沿着原路返回被雷达天线接收，接收机对微弱的回波信号进行放大、滤波、解调等一系列精细处理，提取出目标的距离、方位、速度等关键信息。这一过程如同向黑暗中投掷石子，通过聆听回声来判断周围物体的位置
