Using LS-ESPRIT Algorithm to Estimate the DOA Of Coherent Source via Virtual Array Transformation
Considering that most signals exhibit coherent sources caused by multipath propagation are often encountered in a variety of wireless communication systems. propose an improved algorithm to coherent sources via virtual array transformation. The method are both increasing the numbers of signals and solving the problem of direction finding to coherent signals. Under a lower signal to noise ratio (SNR), it has ability to detect and resolve more coherent and incoherent sources using fewer sensors. The simulation results show that the method is efficient.
