电离层条件本质上是多变的，可能会对在3-30 MHz范围内的高频(HF)频段进行的传输造成破坏性干扰。这带来了一个问题，因为HF频段是各种应用(即紧急、军事)的关键频率范围。为了管理这些动态条件，应该在发送器和接收器上实施智能技术，以适当地维护可靠的通信。在本文中，我们介绍了一种认知高频收发机的组件推导工作，该组件具有运行在发射机和接收器上的称为认知引擎(CES)的代理。在发射机，认知被用来确定最大化吞吐量的调制和编码技术的组合。在接收端，进行认知以得出均衡的最佳参数(即抽头长度、步长、滤波器类型等)。结果表明，各个部件能够满足其目标。还提供了对与自动链路建立(ALE)协议的认知方法的开发有关的最新研究工作的综述，ALE协议是高频站的一种常见的组网方法。
Ionospheric conditions are variable in nature and can cause destructive interference to transmissions made in the High Frequency (HF) band, which ranges from 3-30 MHz. This poses a problem as the HF band is a critical fre- quency range for various applications (i.e. emergency, military). To manage these dynamic conditions, intelligent techniques should be implemented at the transmitter and receiver to properly maintain reliable communications. In this paper, we present work deriving components of a cognitive HF transceiver with agents called cognitive engines (CEs) operating at the transmitter and receiver. At the transmitter, cognition is employed to determine the combination of modulation and coding techniques that maximize throughput. At the receiver, cognition is implemented to derive the best parameters for equalization (i.e. tap length, step size, filter type, etc.) Results are presented showing that the individual components are able to satisfy their objectives. A discussion is also provided surveying recent research efforts pertaining to the development of cognitive methods for the Automatic Link Establishment (ALE) protocol, a common networking methodology for HF stations.
