On the sphere-decoding algorithm II. Generalizations, second-order statistics, and applications to communications

In Part I, we found a closed-form expression for the expected complexity of the sphere-decoding algorithm, both for the infinite and finite lattice. We continue the discussion in this paper by generalizing the results to the complex version of the problem and using the expected complexity expression...
