Receiver for direct-to-device connectivity via a satellite swarm

Abstract

A system and method for mitigating intra-beam interference including: receiving a desired beam and interfering beams transmitted by a satellite swarm; dividing the interfering beams into an intense set, a strong set, and a noise-floor set based on intensity of the interfering beams to mitigate intra-beam interference; decoding symbols from the strong set into a subtractive-cancellation set and the intense set into an optimal-Bayesian set; subtracting symbols of the subtractive-cancellation set; and addressing symbols of the optimal-Bayesian set in an optimal-Bayesian fashion, wherein the desired beam and the interfering beams comprise an Orthogonal Frequency-Division Multiplexing (OFDM) transmission precoded with beamforming weights. A system and method for beamforming at a satellite swarm by realizing a distributed array to jointly generate beams aimed at selected coverage areas is also described.
