以比吸收率为约束条件、设备总速率最大化为目标,提出一种适用于多天线上行传输的预编码设计方案。该方案在提高频谱效率的同时,兼顾了比吸收率对传输功率的影响,从而将比吸收率约束提前到产品设计和优化之中,减少了后期对比吸收率的评估依赖。通过仿真结果表明,这种算法不仅保证了比吸收率在最大允许范围内,而且还大大提升了设备性能。

Taking specific absorption rate (SAR) as constraint and total rate maximization as object, a precoding scheme suitable for MIMO uplink transmission is proposed in this paper. As the proposed scheme considers both the enhancement of spectrum efficiency and the impact of SAR on transmission power, it reduces the dependence on SAR evaluation mainly because SAR is put in product design and optimization in advance. Simulation results reveal that the proposed scheme not only guarantees SAR within the maximum range, but also greatly improve device performance.
