Doppler-shift estimation of flat underwater channel using data-aided least-square approach

International Journal of Naval Architecture and Ocean Engineering, 2015
In this paper we proposed a dada-aided Doppler estimation method for underwater acoustic communication. The training sequence is non-dedicate, hence it can be designed for Doppler estimation as well as channel equalization. We assume the channel has been

Artificial intelligence chatbots mimic human collective behaviour

British Journal of Psychology, Volume 117, Issue 2, Page 761-776, May 2026.
Abstract Artificial Intelligence (AI) chatbots, such as ChatGPT, have been shown to mimic individual human behaviour in a wide range of psychological and economic tasks. Do groups of AI chatbots also mimic collective behaviour? If so, artificial societies of AI chatbots may aid social scientific research by simulating human collectives.
