Joint Physical Layer Coding and Network Coding for Bi-Directional Relaying
Abstract-- We consider the problem of two transmitters wishing to exchange information through a relay in the middle. The channels between the transmitters and the relay are assume...

Network Coding for Two-Way Relay Channels using Lattices
—In this paper, we propose a network coding using a lattice for the two-way relay channel with two nodes communicating bidirectionally through a relay, which we call modulo-andfo...

Approximately achieving Gaussian relay network capacity with lattice codes
Abstract--Recently, it has been shown that a quantize-mapand-forward scheme approximately achieves (within a constant number of bits) the Gaussian relay network capacity for arbitr...

The Case for Structured Random Codes in Network Capacity Theorems
Random coding arguments are the backbone of most channel capacity achievability proofs. In this paper, we show that in their standard form, such arguments are insufficient for pro...

The Invariants of the Clifford Groups
The automorphism group of the Barnes-Wall lattice Lm in dimension 2m (m = 3) is a subgroup of index 2 in a certain "Clifford group" Cm of structure 21+2m + .O+ (2m, 2). ...
