Hierarchical codebook
Webto estimate different MPCs, we use dynamic hierarchical codebook which is updated according to the estimated MPCs. To summarize, our contribution mainly includes: 1) A general-ized hierarchical codebook design method is firstly proposed. 2) Then based on this method, we propose a beam training method which dynamically updates the … Web1 de ago. de 2024 · The hierarchical multi-resolution codebook for channel estimation was proposed in [24]. The algorithm could efficiently detect the different parameters of mmWave channel with a low training overhead. The authors in [25] further proposed a beam design method by using the Fourier series.
