| 摘 要： | 根据OBE算法原理,提出一种智能天线自适应波束形成盲算法。首先建立自适应算法的信号模型,讨论了算法的结构,该算法是建立在解扩、重扩判决指导上,对均方误差准则下的最优权值进行迭代估计;然后分析了OBE算法的原理,在此基础上构建了自适应波束形成的迭代式。最后对算法的性能进行了仿真,仿真结果表明:该算法达到了自适应波束形成的要求,与LS-DRMTA算法相比具有更佳的收敛和输出性能。

| Abstract: | A blind beamforming algorithm based on OBE algorithm is presented.First,the signal model of adaptive algorithm is constructed according to the principle of smart sntennat.Second,the structur of the algorithm is discussed,and the algorithm is based on despread respread judging direction.The optimal weight is iteratively estimated on the mean square error(MSE)criterion.Third,the principle of OBE is studied,and the iterative equation of adapive beamforming is constructed.Last,the performance of the algorithm is simulated.It is shown from simulation results that the algorithm satisfies the require ments of adaptive beamforming,and has better convergence and output performances than LS-DRMTA. |
