无线通信

无线通信编码、调制、相关信号处理和算法。


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

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,CRC级联polar(CRC-polar)是这种情况下的一种经典的改进方案。PCC-polar是CRC-polar的更一般形式,通过优化构造,PCC-polar的性能可以进一步超越CRC-polar。[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]
