摘要
在大规模MIMO 系统中，全复杂度单一基带预编码（如全复杂度破零预编码FC-ZF）需要与天线阵元数目相同的射频链路，进而以高复杂度的硬件实施为代价，混合预编码（HP）技术可以大大降低射频链路数，且性能上接近全复杂度单一基带预编码技术，因此HP技术具有较高的研究价值。提出的自适应数字—模拟域混合预编码（自适应混合预编码/AHP）技术较传统数字—模拟域混合预编码（传统混合预编码）技术可以进一步有效地降低硬件的复杂度，并将其与V-BLAST技术相结合，可以同时获得阵列增益和复用增益。仿真结果表明，提出的方案具有较高的频谱效率、较低的硬件复杂度及比较理想的误码率性能。
Abstract
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 hybrid precoding can reduce the number of RF chain heavily and approach the performance of the FD-BP
so the hybrid precoding for massive MIMO is necessary and worth studying. The adaptive digital and analog hybrid precoding（AHP）can further reduce the hardware complexity compared with the conventional digital and analog hybrid precoding （conventional hybrid precoding）and which combined with V-BLAST can get the array gain and multiplexing gain simultaneously. Simulation results confirm the proposed scheme can obtain the higher spectral efficiency
the lower hardware complexity and more ideal BER performance.
