无线通信

无线通信信道编码、调制、相关信号处理和算法。

信道编码

信道编码是通信系统的核心，其发展经历了经典线性分组码、卷积码、Turbo码、LDPC码和极化码（Polar）码等多个阶段新。未来通信系统需要面向更多不同特征的信道和场景，这对信道编码技术提出了新的挑战。



物联网和M2M

万物互联是未来的发展趋势。物联网依赖无线通信技术的支撑，尤其需要能实现高可靠、低延时、低功耗、低成本、和远距离数据传输的低功耗广域网无线通信（LPWAN）新技术。



大规模多天线技术（Massive MIMO）

多天线已经是当今无线通信的关键特征之一，未来通信设备的天线数量将进一步增加，达到惊人的数量。大规模多天线系统可以支持对频谱资源的高度空间复用，实现显著的容量提升。显然，在容量增益和实现复杂度之间实现平衡是一个困难的问题。



滤波器组多载波技术（FBMC）

作为当今无线通信标准大多采用的多载波技术，正交频分复用（OFDM）不能适应一些不断涌现的无线通信新场景，例如机器类通信、低时延高可靠通信、抗干扰通信和认知无线电。FBMC弥补了OFDM的不足，是未来无线通信最值得关注的新波形技术之一。



智能/认知无线电

无线电频谱是至为宝贵的自然资源。未来无线通信需要越来越多的频谱，然而可供分配的频谱资源已经濒临枯竭。因此，频谱资源的共享和分享是未来的必然发展趋势，基于机器学习和人工智能的认知无线电是实现这一未来的核心技术。




研究成果

基于大规模多天线阵列的免授权随机接入技术（mGFRA）

基于大规模多天线阵列的免授权随机接入（缩写：mGFRA）是一种新型的低功率广域网（LPWAN）技术。mMIMO-GFRA可以看成是多信道时隙ALOHA与mMIMO接收机的结合；其核心思想是在最小化用户接入信令开销的同时，利用频分复用和空分复用以支持大量用户的并行接入。[详情]


校验级联极化码（Parity-Check-Concatenated Polar Codes，PCC-polar）

Polar码是目前唯一被证明可以达到香农容量限的结构化编码方法，已经被确定为5G的控制信道编码方案。然而，在码长较短的情况下，因为比特信道极化不充分，导致polar码性能损失。PCC-polar是利用未充分极化比特信道的一般形式，通过优化构造，PCC-polar相比传统polar码可获得可观的性能提升。[详情]


可反转子集LDPC码（IS-LDPC）

OFDM多载波通信信号的幅度起落很大，也即具有很高的峰值均值功率比（PAPR）。抑制PAPR有助于提升功放效率，减少信号的带内失真和带外干扰。IS-LDPC码作为一种信道编码方案，既具有接近香农极限的纠错性能，又具有抑制信号PAPR的能力。[详情]


FBMC拖尾抑制

滤波器组多载波（FBMC）信号前后会产生较长的拖尾，导致通信系统频谱利用率明显降低。基于虚拟符号的信号拖尾抑制方法能够使得拖尾起始点之后的信号大部分被抵消，同时旁瓣能量较低，不会造成带外频谱泄露。[详情]
