TLDR
Numerical results show that causal knowledge of the interference provides more than 3 dB improvement in performance in certain scenarios over a scheme that does not use interference cancellation.Abstract:
In this paper, we present a practical application of dirty paper coding (DPC) for the Gaussian cognitive Z-interference channel. A two stage transmission scheme is proposed in which the cognitive transmitter first obtains the interference signal from the primary transmitter and then uses DPC to improve the performance of the cognitive link. Numerical results show that causal knowledge of the interference provides more than 3 dB improvement in performance in certain scenarios over a scheme that does not use interference cancellation. Results are also shown when the cognitive transmitter operates in both half-duplex and full-duplex modes.read more

TL;DR: Numerical results show that the derived achievable rate region contains the available rate region in the literature, and the sum rate has a concave relation with the number of channel uses in the listening phase.

Orthogonal space-time block coding over dirty paper channel
TL;DR: It is analytically prove that the outage capacity of the multiple input multiple output (MIMO) which is affected by interference, that is non-causally available as well as the channel state information (CSI) for all users at the transmitter, has the free interference outage capacity.

A simple rate-1/2 co-decoding scheme for Writing on Dirty Paper
Matteo Mazzotti,Marco Chiani +1 more
TL;DR: This paper proposes a simple co-decoding scheme for a Writing on Dirty Paper scenario, where the transmitted signal is affected by interference known by the transmitter and thermal noise, and shows that it is possible to reach BER performance within 1.2-1.3 dB from the correspondent LDPCC's in AWGN channels.

Binary decoding of concatenated turbo codes and space-time block codes for quaternary modulations
TL;DR: A general formulation for STB decoding based on a least squares criteria is given in order to allow binary turbo decoding while using quaternary modulations such as QPSK, which results in a higher global rate at no complexity cost.

TL;DR: This work proposes to implement the random binning concept using only binary LDPC and binary convolutional codes, and shows that this system achieves similar performance to the state-of-the-art, high-order-alphabet LDPC-based systems while demonstrating significant advantages in terms of complexity and flexibility of system design.
