Abstract: In frequency-division duplexing (FDD) massive multi-input multi-output (MIMO) systems, the codebook-based beamforming has been widely considered to overcome the overhead of channel state ...

Abstract: Codebook design utilizing channel statistics is an effective solution to reduce feedback overhead in frequency-division duplexing (FDD) multiple-input ...

Hi, I tried to use both codebook loss and commitment loss instead of EMA update, but I was confused about how to use codebook loss. If 'learable_codebook' is True, then 'commit_quantize' is not ...

Neural networks have become indispensable tools in various fields, demonstrating exceptional capabilities in image recognition, natural language processing, and predictive analytics. However, there is ...

In this paper, we present a theoretical codebook design method for VQ-based fast face recognition algorithm to im-prove recognition accuracy. Based on the systematic analysis and classification of ...
