Cooperative Beamforming With Artificial Noise Injection for Physical-Layer Security
IEEE Access, 2023 In the sixth-generation (6G) communications, how to deploy and manage massively connected Internet-of-Things (IoT) nodes will be one of the key technical challenges, because 6G is expected to provide 10 times higher connection, compared to 5G.

Distributed Transmit Beamforming Using Feedback Control [PDF]
IEEE Transactions on Information Theory, 2010 A simple feedback control algorithm is presented for distributed beamforming in a wireless network. A network of wireless sensors that seek to cooperatively transmit a common message signal to a Base Station (BS) is considered. In this case, it is well-known that substantial energy efficiencies are possible by using distributed beamforming.

An adaptive protocol for distributed beamforming.
, 2011 We study distributed adaptive beamforming in networks of wireless nodes. In particular, we observe that for the synchronisation of carrier phases, distinct algorithmic configurations are optimal in various environmental settings and propose a protocol that utilises organic computing principles to find optimum parameters.

Asymptotic analysis of distributed multi-cell beamforming [PDF]
21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010 We consider the problem of multi-cell downlink beamforming with N cells and K terminals per cell. Cooperation among base stations (BSs) has been found to increase the system throughput in a multi-cell set up by mitigating inter-cell interference. Most of the previous works assume that the BSs can exchange the instantaneous channel state information ...
