Channel Estimation Algorithm for G3-PLC Systems Based on Variable Step Size Matching Pursuit
为合理利用电力线信道的稀疏特性,提高G3-PLC系统通信的可靠性,基于压缩感知(compressed sensing,CS)理论,提出一种稀疏度自适应的变步长前向后向匹配追踪(sparsity adaptive variable step size forward-backward pursuit,SA-VSSFBP)算法.该算法在前向后向匹配追踪算法(forward-backward pursuit,FBP)的基础上引入变步长自适应的思想,于迭…查看全部>>
In order to leverage the sparse characteristics of power line communication channel and improve the reliability of G3-PLC system communication,this paper proposes a sparsity adaptive variable step size forward-backward pursuit (SA-VSSFBP) algorithm based on the theory of compressed sensing (CS). This algorithm builds upon the forward-backward pursuit (FBP) algorithm and introduces the concept of variable step size with adaptivity. It employs a large step siz…查看全部>>
