An Improved Wideband Covariance Matrix Sparse Representation (W-CMSR) Method for Wideband Direction of Arrival Estimation Using Simulated Annealing

In this paper, we optimize the size of aperture and number of sensors for Wideband Covariance Matrix Sparse representation (W-CMSR) method for Wideband Direction of Arrival estimation using Simulated Annealing. The performance of W-CMSR is obtained with initial number of sensors and aperture size. Then, we find the performance of W-CMSR with optimized number of sensors and aperture size using simulated annealing. We observe that same performance of W-CMSR is obtained with reduced number of sensors and aperture size by using simulated annealing.
