摘要:

在现有收发机损耗模型基础上以最小化最差用户均方误差或者最小化用户均方误差之和为优化目标,设计一种考虑收发机残留损耗的多小区多用户下行链路波束成形算法。通过将优化问题转化成二阶锥规划的标准形式,并设计分层优化迭代算法来求解原始问题。数值仿真表明,相对于传统收发机的波束成形算法而言,所提算法将极大地减小收发机损耗对系统性能的影响,进而显著提高系统性能。

Abstract:

Multi-cell multi-user downlink beamforming schemes considering transceiver impairments were developed,with the objective of minimizing the maximum mean square error (MSE) and the sum of MSE of all users.The optimiza-tion problem was transformed into a second-order cone programming(SOCP) standard form,and a hierarchical iterative algorithm was developed to solve the original problem.Compared with the traditional beamforming methods developed for ideal transceivers,numerical results show that our proposed optimization algorithms greatly reduce the impact of im-pairments and improve the system performance.

Key words: transceiver impairment, beamforming, convex optimization, mean square error
