基于最大化信干噪比的广播信道干扰消除算法
An interference mitigation algorithm for broadcast channels based on Max-SINR
摘要
Abstract
The performance of distributed interference mitigation algorithms for broadcast channels was studied,and a new interference mitigation algorithm based on dynamic power allocation for multi-user multi-antenna broadcast channels was proposed.The new algorithm uses the trace of the channel correlation matrix to calculate the power allocation,and uses the method of maximizing the signal interference noise ratio (SINR) to obtain the precoding matrix and the receiving filter matrix.The numerical simulation showed that the proposed dynamic power allocation algorithm outperformed the equal power allocation algorithm in medium/high load scenario,and solved the bottleneck effect;the proposed algorithm gave no obvious gain compared to the prior art in low load scenario.However,the needs for low load application are not strong,the proposed scheme is a practical method for channel interference mitigation.关键词
