Real-Value Space ESPRIT Algorithm and Its Implement

Real-value space ESPRIT (RVS-ESPRIT) algorithm transforms complex data into real data, via constructing real-value transformation, so as to reduce computation, through rearranging data and forward-backward averaging improves the performance and precision of estimating parameter. This paper analyses the rotational invariance principle of RVS-ESPRIT algorithm, the relationship between RVS-ESPRIT and complex space ESPRIT, and give the implementing algorithm of RVS-ESPRIT. Its performance is compared with other algorithm by simulation
