Cooperative decode-and-forward relaying for secondary spectrum access
TL;DR: The paper provides a full characterization of the Markov Chain describing the protocol behavior and a closed form expression for the stationary distribution of the chain and exact computation or tight approximations for the outage probabilities for all states of theChain are derived.

Performance bounds for two-way amplify-and-forward relaying
TL;DR: This paper derives the harmonic mean of two independent gamma distributed random variables which have the same shape parameter but different scale parameters as well as an upper bound for the pairwise error probability for the proposed two-way OSTBC scheme and shows that the average sum rate is further improved compared to the single antenna case and a diversity order of two is achieved.

Adaptive two-way relaying and outage analysis
TL;DR: A simple adaptive protocol is considered in the two-way relaying scenario, which switches between AF and DF depending on the decodability of the two bi-directional data streams at the relay, and it always outperforms the non-adaptive schemes.

Cooperative Spectrum Sharing Protocol with Secondary User Selection
TL;DR: Theoretical and simulation results confirm the efficiency of the proposed spectrum sharing protocol, and it is shown that both primary and secondary systems are able to achieve better outage performance with increasing M.

TL;DR: By using a space time block code (STBC) design in two time phases in thesecondary system, the subsequent interference from the secondary system to the primary system and vice versa can be completely removed and it is possible to achieve spectrum access for secondary system without compromising on the performance of thePrimary system.
