3. For modern communication system, in order to save spectrum resources and boost spectrum efficiency, some kinds of complex digital modulation are used, for example QPSK, QAM, OFDM, which are not constant envelop modulation. Furthermore the peak to average power ratio is very big. Taking WCDMA for example, PAR is 6～9dB at 0.01%probability on the CCDF.

由于现代通信平台为了提升频谱利用率，采用了诸多复杂的数字调制技术QPSK手机如何查wcdma，QAM，OFDM，这些都是非恒定包络的调制方法，并且峰值和平均值相差较大，通常功率放大器采用电压回退的方式来超过线性度的提高，但是随着功耗的回退，放大器的功耗附加效率也会大大的减少。

5. Adding the optional QoS parameters of the relevant message of the radio network subsystem application part and the node B application part makes the node B and the drift radio network controller know the QoS information in the application layer of the dedicated transmission channel frame protocol data unit. Based on the QoS parameter, the QoS differentiation of the DCH FP PDU Iub/Iur interface transmission network layer is carried out.

本发明公开了一种应用于WCDMA系统IP传输无线接入网Iub/Iur接口的客户面存储网络层服务品质区别的方式，通过在无线网络子系统应用部分、节点B应用部分相关消息中提高可选的QoS参数，让节点B、漂移无线网络控制器知道专用传输信道帧协议数据单元应用层的QoS信息，依据这个QoS参数来进行DCH FP PDU Iub/Iur接口传输网络层的QoS区分。

6. Analyzing the array pattern, we show that the interference of other sectors, also to be MAI, can be effectively suppressed by the array antennas for a sectored UTRA TDD of WCDMA system.

对阵列模式进行预测，证明分扇区UTRA TDD模式的WCDMA系统可有效促进多址干扰。

7。 The WCDMA network shares system bandwidth, and is a self-interfering system。 The WCDMA network planning should consider the interference control in addition to network coverage。 Therefore, it requires more precise propagation models in contrast with the GSM network planning。 The WCDMA network supports multiple services, and its support of high-speed services makes the WCDMA network cell coverage smaller and the coverage radius is only hundreds of meters or less。 For the dense urban environment, in such small coverage radius, the electric wave propagation paths from the transmitter to the receiver include direct wave, reflective wave on the vertical surface of the building, diffractive waves on the vertical edge of the building, and the diffractive waves on the horizontal edges of the building, and the high-order reflective/diffractive waves (the influence of second-order reflective/diffractive waves is significant), as shown in Figure 1。 Therefore, the features and distribution of the buildings are critical to the signal propagation, and affect the receiving signal strength significantly。

WCDMA网络是共享平台带宽的，是一个自干扰系统，因此WCDMA网络规划除了必须考量网络覆盖，还要考虑干扰控制，因此相对于GSM网络规划必须非常准确的传播模型；同时WCDMA网络支持多种业务，对高速数据业务的支持并且WCDMA网络小区的覆盖范围较小，半径仅为几百米甚至最小，对于密集城区环境中那样小的长度内，从发射机到接收机的主要电波传播模式包含直射波、在建筑物垂直面上的反射波、在建筑物垂直棱上的衍射波、在建筑物水平棱上的衍射波或者高阶的反射/衍射波(其中二阶反射/衍射波的影响非常大)，如以下图1所示，可见建筑物的特点跟分布对信号传播起着关键作用，对接收信号密度有着十分重要的影响。

8. And the basic principles of coding and decoding of Turbo Codes are discussed, the MAP and Max-Log-MAP algorithms which are suitable for the Turbo Code are detailedly discussed. Then, because the interleaves technology has important influence in radio channel, the article provides the detailed scheme of implementation in WCDMA system. Besides providing a series of simulation illuminates the influence of interleave-length to the Turbo-code performance.

由于交织技术是为了抵抗无线信道的串扰以及衰落的制约而采用的时间分集技术，在WCDMA的编码过程中带有重要的作用，所以本文对交织技术在WCDMA系统中的应用也做了具体介绍，并且借助仿真说明了交织长度对Turbo码性能的影响。
