In the past decade, artificial intelligence (AI) and machine learning (ML) have undergone significant transformations—convolutional neural networks (CNNs) and recurrent neural networks (RNNs) are transitioning to Transformers and generative artificial intelligence (GenAI). This transformation is driven by the industry’s urgent demand for models that are efficient, accurate, context-aware, and capable of handling complex tasks.Initially, AI … Read more
In communication design, considering the flexibility of the protocol often leads to designing protocols as “variable length”. An example is shown in the figure below: the communication protocol frame of the Ruimi LoRa terminal. If a system receives the above “variable length” protocol frame, there will be a challenge—how to efficiently receive and parse it. … Read more
