Antenna Array Signal Processing for Quaternion-Valued Wireless Communication Systems
It addresses a missing link in quaternion-valued wireless communications by providing effective signal processing algorithms for practitioners in this domain.
This work develops quaternion-valued signal processing algorithms for channel equalization and beamforming in quaternion-valued wireless communication systems, deriving the quaternion-valued Wiener solution for block-based calculation.
Quaternion-valued wireless communication systems have been studied in the past. Although progress has been made in this promising area, a crucial missing link is lack of effective and efficient quaternion-valued signal processing algorithms for channel equalisation and beamforming. With most recent developments in quaternion-valued signal processing, in this work, we fill the gap to solve the problem and further derive the quaternion-valued Wiener solution for block-based calculation.
