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. WebThis allows for more flexible hierarchical codebook design [26]. Such codebooks can also be designed with logical sub-arrays only, which only requires an analog array [27]- [29] .
