Asymptotic performance of Dirichlet rotated polar quantizers (Corresp.)
Peter F. Swaszek · IEEE Transactions on Information Theory · 1985
An upper bound to the asymptotic mean-square error performance of optimized rotated polar quantizers is presented for a circularly symmetric random input. This form of quantizer is of interest because it has a scalar implementation and has been shown, for a small number of levels with a Gaussian source, to have much better performance than either the rectangular or polar schemes previously documented.
