| 摘 要： | 目前高校通信类专业所用实验设备主要完成调制、交织、信道编码和系统信令实验,较难配合3GPP标准来完成教学和科研及课程设计及毕业设计的任务。在充分研究3GPP标准文档后,在自主开发的ARM和DSP单板上完成了3G系统及4G系统的信道编解码。文中对单板结构进行了研究,对物理层协议的信道编解码功能及算法的具体实现进行了研究,包括CRC校验,卷积编码,viterbi解码,速率匹配,交织,信道复用以及传输信道到物理信道的映射等。较好地配合了教学和科研工作,对3GPP标准的演进过程的跟踪教学与研究也有一定作用。

| Abstract: | Experimental equipment is mainly used in communication engineering in colleges and universities, interleaving, channel coding and modulation system signaling experiment, difficult to cooperate with the 3GPP standards to complete the teaching and scientific research and the course design and graduation design task. After fully research 3GPP standard document on the independent development of ARM and DSP board finished 3G and 4G system of channel codec. In this paper, we studied the veneer structure, channel decoding function of the physical layer protocol and algorithm implementation are studied, including the CRC check, convolutional coding and viterbi decoding, the rate of match, interweave, channel multiplexing and mapping of transmission channel to the physical channel. Better cooperate with the teaching and scientific research work, the evolution process of the 3GPP standard tracking teaching and research also has certain effect. |
