Abstract: In this paper, we propose a physical layer network coding technique combined with asynchronous code division multiple access (CDMA). We consider a scenario where there are multiple pair of nodes with a single relay, and each pair of nodes exchange information asynchronously. With the assumption of asynchronous transmission, there is a trade-off between the number of nodes and the inter-user interference because the spreading codes are not orthogonal to each other. The BER and the throughput of the system are analyzed, and simulations are performed to verify the results. It is shown that physical layer (analog) network coding improves throughput compared to the conventional routing protocol with large $E_b/N_0$, low number of users, and large spreading factor.

Network information flow
TL;DR: This work reveals that it is in general not optimal to regard the information to be multicast as a "fluid" which can simply be routed or replicated, and by employing coding at the nodes, which the work refers to as network coding, bandwidth can in general be saved.

Physical Layer Network Coding
TL;DR: This paper proposes a physical-layer network coding (PNC) scheme to coordinate transmissions among nodes that makes use of the additive nature of simultaneously arriving electromagnetic (EM) waves for equivalent coding operation and demonstrates its potential for boosting network capacity.
