  • Abstract
    Let (X_1,Y_1), \\cdots ,(X_N, Y_N) be N independent pairs of circularly symmetric random variables, A simple expression is derived for the even moments of the (Euclidean) norm of the vector sum (X_1, Y_1) + \\cdots + (X_N, Y_N) in terms of the moments of (X_i ^2 + Y_i ^2)^{1/2}, i = 1,\\cdots ,N . As an application of our results we find an expression for the moments of the "envelope" of a sum of randomly phased cosinusoids.
