Description

一种无线通信方法和设备Wireless communication method and device 技术领域Technical field
本发明涉及无线通信***中的无线信号的传输方案，特别是涉及基于数字调制的无线信号的传输方法和装置。The present invention relates to a transmission scheme of a wireless signal in a wireless communication system, and more particularly to a method and apparatus for transmitting a wireless signal based on digital modulation.
背景技术Background technique
传统的基于数字调制方式的无线通信***，例如3GPP(3rd Generation Partner Project，第三代合作伙伴项目)蜂窝***以及无线局域网通信***(如Wifi，Wimax)中，每一个或者多个二进制比特(在发射机侧)被调制成一个星座点符号，即映射到星座图(Constellation)中的一个星座点(Constellation Point)，然后被发送。接收机根据接收到的星座点符号判断其映射的星座点，进而确定相应的二进制比特。A conventional digital modulation-based wireless communication system, such as a 3GPP (3rd Generation Partner Project) cellular system and a wireless local area network communication system (such as Wifi, Wimax), each or more binary bits (in The transmitter side is modulated into a constellation point symbol, that is, mapped to a constellation point in the constellation and then transmitted. The receiver determines the constellation points of its mapping according to the received constellation point symbols, and then determines the corresponding binary bits.
为了提高无线信号传输的鲁棒性，发射机广泛采用信道编码引入冗余比特。常用的信道编码包括卷积码，Turbo码，LDPC(Low Density Parity Check Code，低密度奇偶校验码)码。相应的，接收机采用信道译码恢复出***比特。常用的信道译码包括Viterbi译码，Log_Map译码等等。In order to improve the robustness of wireless signal transmission, transmitters widely use channel coding to introduce redundant bits. Commonly used channel coding includes convolutional codes, Turbo codes, and LDPC (Low Density Parity Check Code) codes. Correspondingly, the receiver uses channel decoding to recover the systematic bits. Commonly used channel decoding includes Viterbi decoding, Log_Map decoding, and the like.
为了进一步提高传输效率，AMC(Adaptive Modulation and Coding，自适应编码调制)和HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)作为两项关键技术在无线通信中被广泛采用。上述两项技术使得发射机能够根据无线信道质量选择合适的调制方式(即星座图)以及信道编码速率，最大化***容量。In order to further improve transmission efficiency, AMC (Adaptive Modulation and Coding) and HARQ (Hybrid Automatic Repeat reQuest) are widely used as two key technologies in wireless communication. The above two techniques enable the transmitter to select the appropriate modulation scheme (ie, constellation) and channel coding rate based on the quality of the radio channel to maximize system capacity.
AMC和HARQ所面临的一个挑战是：发射机在无法准确获得无线信道质量的条件下可能无法选择合适的调制方式以及信道编码速率。无法准确获得无线信道质量的原因包括(但不限于)：突发的干扰，小尺度衰落特性的快速变化，接收机反馈延时等等。One of the challenges faced by AMC and HARQ is that the transmitter may not be able to select the appropriate modulation scheme and channel coding rate without being able to accurately obtain the quality of the radio channel. Reasons for not being able to accurately obtain wireless channel quality include (but are not limited to): bursty interference, rapid changes in small-scale fading characteristics, receiver feedback delay, and the like.
