| Abstract(in English) | A link adaptation scheme is devised for vector-perturbation (VP) zero-forcing beamforming (ZFBF) MIMO precoding and a link-adaptable VP-ZFBF precoder is applied to multi-point three-dimensional (3D) beamformers to be used in mmWave-band mobile communication systems. Channel coding schemes used in current systems, e.g., turbo codes, possess systematic code structures. The perturbation gain can thus be predicted by searching for perturbation vectors for the symbol vectors mapped from information bits. On the basis of this principle, we constructed an efficient iterative modulation-and-coding-set (MCS) selection procedure for VP-ZFBF precoding. Simulation results demonstrate that our proposed scheme suitably passed on the perturbation gain to the selection of higher MCS and thus achieved high throughputs by incorporating with multi-point 3D-beamformers. |
