Convolutional Lattices

Real convolutional lattices over the ring of integers Z are considered in this paper. We study the stability of convolutional lattices under sphere decoding. A new stable family of time-alternating convolutional lattices is proposed. The structure, the parameters, and a performance example are shown for time-alternating convolutional lattices. These lattices can be used as constituent blocks in concatenated coded modulations for control and communication.
