Overview

Performance modeling demonstrates improved spectral efficiency in multi-antenna satellite downlinks, indicating superior reliability over conventional access schemes without complex receiver stages.

Key Points

To evaluate the outage probability and ergodic capacity of a partial power-frequency multiple access protocol for multi-antenna satellite-to-terrestrial downlink systems.
Designed a hybrid scheme combining power-domain superposition and orthogonal bandwidth partitioning for multi-antenna satellites and single-antenna ground terminals.
Derived closed-form expressions and high-SNR asymptotic approximations for outage probability and ergodic capacity over Shadowed-Rician fading channels.
Validated theoretical derivations against conventional orthogonal and non-orthogonal multiple access benchmarks via Monte Carlo simulations.
High-SNR analytical expressions established the diversity orders and capacity ceilings dictated by power and frequency allocation parameters.
The proposed access framework yielded higher spectral efficiency and reduced outage probabilities relative to standard benchmark schemes under matched power and bandwidth constraints.
