Vector quantizers based upon the A and D lattices are explored using the mean-square error (mse) fidelity criterion for the independent identically distributed (i.i.d.) sources with normal, Laplacian, and gamma probability density functions. Code books are studied for uniform coding rates of up to 2 bit/sample and from two to four dimensions. The quantizer performances are compared to optimal (nonuniform) Lloyd-Max quantizers.
