This paper dresses the implementation of an orthogonal frequency division multiplexing (OFDM) based multicarrier UWA communication system adopting a novel transform called T-transform. It combines the Walsh-Hadamard transform (WHT) and the discrete Fourier transform (DFT) into a single fast orthogonal unitary transform which increases channel diversity order without sacrificing any throughput. The...
Physical layer network coding (PNC) is a novel technique that allows two users to exchange messages in a wireless network. PNC takes place at a relay node and exploits the interference caused by incoming signals from the two users to increase throughput. In this paper, the performance of a two-way relay network employing PNC is evaluated with three types of error-correcting codes used at the source...
