For a receiver requiring a lower constellation, at first the low-level constellation is derived by exploiting the a priori information, as described in Section 4.3.
In this paper, by exploiting the features of M-PSK and M-QAM constellations, we first have designed two novel low-complexity soft-output algorithms based on the existing hard-decision detection algorithms.
Moreover, a fast and hardware-friendly node enumeration scheme is developed to further reduce the processing delay by exploiting the geometric property of the quadrature amplitude modulation (QAM) constellation.
The purpose of the consortium is to contribute to the optimal science return from the Swarm mission by a coordinated effort to exploit the constellation aspects of this unique mission.
The key novelty is that GL-PIC employs more reliable estimates by exploiting prior knowledge of the constellation points.
Hundreds of other startups are now exploiting the 100X cost savings of microsat constellations to colonize space.
Astronomers, exploiting the transparency of the atmosphere, study unthinkably distant constellations whose light has traveled for eons before reaching us.
Exploiting the community.
Constellation nesting fully exploits the power on each link by using the a priori information in times of decoding.
Subcarrier grouping and linear constellation precoding can exploit the multipath diversity with low-complexity decoding, which has been applied to single-hop or dual-hop OFDM systems [9 12].
