参考3GPP相关标准并根据LTE技术特征和关键特性,对下行链路级进行设计,包含以下步骤:比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道,还需仿真相应的信道模型。收端则是发端的严格逆过程,对接收信号进行一系列处理,得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

DC-ransmission
多端直流输电系统(multi-terminal DC,MTDC)为解决
大型风电基地功率外送的瓶颈问题提供了一个最佳解决方
案。研究了基于电压源换流器(voltage source converter,VSC)
的多端直流输电系统应用于大规模风电功率长距离外送时
的协调控制策略。通过构建一个四端系统连接两个大型风电
基地及本地电网向远方负荷中心进行功率输送,实现了风电
场的功率汇集和外送。仿真验证了该协调控制策略在大扰动
情况下,不仅能够提高VSC-MTDC系统潮流重新分配的能
力,而且可使风电场对直流网络提供一定功率支撑,增强了
电力系统动态稳定性
(Multi-terminal DC (MTDC) power transmission
system is regarded as the optimal solution scheme to sent out
power from large-scale wind farm. A coordinated control
strategy for voltage source converter (VSC) based MTDC
transmission system applied to long-distance power
transmission from large-scale wind farm is researched. By
means of constructing a four-terminal system connecting two
large-scale wind power bases with local power grid to send out
power to faraway load center, the wind power converging and
sending out by the proposed coordinated control strategy are
implemented. Simulation results show that the proposed
coordinated control strategy not only can improve the ability of
reallocating power flow in VSC-MTDC transmission system
under large disturbance, but also can make wind power base
providing a certain power support to DC transmission network,
thus the dynamic stability of power grid can be enhanced.
