This paper focuses on the question of what needs to be predicted and what processes need
to be understood to predict and forecast space weather conditions that are hazardous to …

Lophelia pertusa and Madrepora oculata are azooxanthellate corals with nearly
cosmopolitan distributions. They form cold-water reefs in the upper bathyal zone on …

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 …

This contribution investigates semi-blind adaptive spatial filtering or equalisation for multiple-
input multiple-output (MIMO) systems that employ high-throughput quadrature amplitude …

A class of constant modulus algorithms (CMAs) subject to a conjugate symmetric constraint
is proposed for blind beamforming based on the uniform linear array structure. The …

A low-complexity semi-blind scheme is proposed for joint channel estimation and data
detection on sphere manifold for multiple-input multiple-output (MIMO) systems with high …

A nonzero residual intersymbol interference (ISI) causes the symbol error rate (SER) to
increase where the achievable SER may not answer any more on the system's …

This contribution revisits blind equalisation for high-order quadrature amplitude modulation
systems using a low-complexity high-performance concurrent constant modulus algorithm …

A single-input-multiple-output (SIMO) channel is obtained from the use of an array of
antennas in the receiver where the same information is transmitted through different sub …

We propose a semi-blind adaptive beamforming approach for wireless systems that employ
high-throughput quadrature amplitude modulation signalling schemes. A minimum number …
