Abstract
In spatial smoothing,the effective correlation among the impinging sources goes to zero only asymptotically with the number of subarrays.Recently,Takao et al.and Paulraj et al. proposed Toeplitzization and adaptively weighted subarray covariance averaging methods, respectively, wherein the impinging sources are perfectly decorrelated whenever the number of subarrays exceeds a minimum value. While both methods achieve the same result, the formulations of the two methods are different. In this communication, we first suggests an alternate formulation of the same problem and then compares the three methods showing that the solutions obtained by them are equivalent.
