We propose a novel mode of operation for Amplify-and-
Forward relays in which the spectra of the relay input and
output signals partially overlap. This partial-duplex relaying mode
encompasses half- and full-duplex as particular cases. By viewing
the partial-duplex relay as a bandwidth-preserving Linear
Periodically Time-Varying system, a spectral efficiency analysis
under self-interference is developed. In contrast with previous
works, self-interference is regarded as a useful informationbearing
component rather than simply assimilated to noise. This
approach reveals that previous results regarding the impact of
self-interference on (full-duplex) relay performance are overly
pessimistic. Based on a frequency-domain interpretation of the
effect of self-interference, a number of suboptimal decoding
architectures at the destination node are also discussed. It is found
that the partial-duplex relaying mode may provide an attractive
tradeoff between spectral efficiency and receiver complexity.

Rain attenuation is among the major impairments for satellite systems operating in the K band and above. In this paper, we investigate the impact of spatially correlated rain attenuation on the performance of a multibeam satellite return link. For a comprehensive assessment, an analytical model for the antenna pattern that generates the beams is also proposed. We focus on the outage capacity of the link, and obtain analytical approximations at high and low SNR. The derived approximations provide insights on the effect of key system parameters {\textendash} like the inter-user distance, the satellite beam radius, or the rain intensity{\textendash} and simulation results show that it fits tightly to the Monte Carlo results. Additionally, the derived expressions can be easily particularized for the single-user case, providing some novel insights.

Multibeam satellite systems are nowadays widely employed, and their use is expected to grow in the next decades. This has raised the interest for signal processing techniques able to mitigate the interference among beams, since they could enable a much more aggressive spectrum reuse. From an engineering point of view, the design of the system must be no longer based on the capabilities provided by the usual physical layer; it should take into account the presence of these interference canceling techniques, predict their performance as accurately as possible -even under a number of impairments and non-idealities- and design accordingly in order to fully exploit them. In this paper, we investigate the effect of a practical impairment of great importance, namely, the attenuation due to the rain, on the performance of a return link which performs MMSE interference canceling. Analytical expressions are derived for a number of performance measures based on the statistical characterization of the rain attenuation.
