一种应用遗传算法的阵列天线共址干扰抑制技术.

Publication Type: Academic Journal

Source(s): Telecommunication Engineering. 2022, Vol. 62 Issue 10, p1514-1518. 5p.

Authors:

Abstract: 针对有限大平台部署多种传感器导致的严重的自干扰问题,提出了一种应用遗传算法实现 的阵列天线共址干扰抑制技术。首先针对同平台上的阵列天线和其他天线建立了辐射和接收模型, 然后将辐射特性和接收机抗干扰特性分别抽象为最优化问题的目标函数和约束条件,最后通过遗传 算法进行最优化求解。该技术在不同辐射角度时能抑制共址干扰,具有一定的工程实用价值。 [ABSTRACT FROM AUTHOR]...

Ergodic Capacity of Space–Time Line Code Systems With Transmit Antenna Selection.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Vehicular Technology. Aug2022, Vol. 71 Issue 8, p9089-9094. 6p.

Abstract: Since a novel diversity technique called a space–time line code (STLC) was invented, previous studies have focused on the analysis of a rate-1 STLC assuming two receive antennas. For the state-of-the-art STLCs with transmit antenna selection (TAS), in ...

Precoding and Scheduling for AoI Minimization in MIMO Broadcast Channels.

Publication Type: Academic Journal

Source(s): IEEE Transactions on Information Theory. Aug2022, Vol. 68 Issue 8, p5185-5202. 18p.

Abstract: In this paper, we consider a status updating system where updates are generated at a constant rate at $K$ sources and sent to the corresponding recipients through a noise-free broadcast channel. We assume that perfect channel state information (CSI) is...
