Dianxin kexue, 2016 In the massive MIMO system, the only full digital baseband precoding（FD-BP）scheme（such as full complexity zero forcing）requires the same number of radio frequency（RF）chains as the number of antenna elements, which leads to extreme high hardware cost, the

Unveiling Mexico's Demographic Transitions
Studies in Family Planning, Volume 56, Issue 4, Page 778-808, December 2025.Abstract This study examines Mexico's fertility transition (1930–2015) and how socioeconomic status (SES), geography, and indigeneity shaped reproductive behaviors. Using net fertility—the number of surviving children under five—we assess how prestige bias (adopting high‐status fertility norms) and conformism bias (aligning with local norms) influenced

A Large-Scale MIMO Precoding Algorithm Based on Iterative Interference Alignment
Cybernetics and Information Technologies, 2014 The performance of Large-scale MIMO system is degraded by Pilot Contamination. In order to reduce Pilot Contamination, a downlink precoding algorithm is put forward, based on Interference Alignment (IA).
