Encoding algorithms for complex approximations in Z(e/sup 2 pi i/8/)
Michael W. Marcellin, T.R. Fischer · IEEE Transactions on Information Theory · 1989
Two algorithms are presented that approximate complex numbers by elements of the algebraic integers of Q(w) where w=e/sup 2 pi i/8/. These algorithms substantially reduce the computational burden. Range and memory requirements are given as a function of the desired accuracy, and expressions are obtained for the number of computations required by each algorithm.>
