The amplify-and-forward cooperative diversity scheme is generalized to the MIMO channel. A family of space-time block codes for a half-duplex MIMO amplify-and-forward fading cooperative channel with N relays is constructed. The code construction is shown to achieve the optimal diversity-multiplexing tradeoff of the channelread more

Optimal Space–Time Codes for the MIMO Amplify-and-Forward Cooperative Channel

TL;DR: This work extends the nonorthogonal amplify-and-forward (NAF) cooperative diversity scheme to the multiple-input multiple-output (MIMO) channel and proves that the Golden code and the 4times4 Perfect code are optimal for the single-antenna and two-Antenna cases, respectively.

Cooperative diversity in wireless networks: Efficient protocols and outage behavior
TL;DR: Using distributed antennas, this work develops and analyzes low-complexity cooperative diversity protocols that combat fading induced by multipath propagation in wireless networks and develops performance characterizations in terms of outage events and associated outage probabilities, which measure robustness of the transmissions to fading.

User cooperation diversity. Part I. System description
TL;DR: Results show that, even though the interuser channel is noisy, cooperation leads not only to an increase in capacity for both users but also to a more robust system, where users' achievable rates are less susceptible to channel variations.

Distributed space-time-coded protocols for exploiting cooperative diversity in wireless networks
J.N. Laneman,Gregory W. Wornell +1 more
TL;DR: This work develops and analyzes space-time coded cooperative diversity protocols for combating multipath fading across multiple protocol layers in a wireless network and demonstrates that these protocols achieve full spatial diversity in the number of cooperating terminals, not just theNumber of decoding relays, and can be used effectively for higher spectral efficiencies than repetition-based schemes.
