Abstract
The Shannon lower bound on the rate distortion function of spherically invariant random vectors and sequences is found, and a condition for its tightness is given. Under this condition, simple upper bounds which are valid over a certain range of distortions are given. Also included is a coding theorem for certain stationary discrete-time spherically invariant sources.
