Jibo Wei · Dianzi xuebao · 2007
In comparison with the multiplex training scheme,superimposed pilot has the advantage of efficient bandwidth and high information rate,thus become more and more attractive.In this paper,the closed form expression of MSE and receive SINR as a function of pilot parameter is deduced,based on the first-order statistic channel estimation algorithm;then an optimal design scheme of superimposed pilot for MIMO systems is proposed to achieve the optimized MSE,receive SINR and PAPR simultaneously;at last the relationship of MSE,receive SNR and pilot parameters is analyzed through simulation,which further validate of optimization scheme.
