Abstract: Systems and methods for adaptive beamforming for a mobile satellite system (MSS). Embodiments described herein provide individual-user-optimized, adaptive beamforming. One example system creates a user beam optimized based either on known user locations or the waveforms received from all cochannel users. The user beam maximizes the signal-to-interference-noise relative to the desired user, both in the forward and return links. The optimization process considers the spatial distribution of all cochannel users in the footprint of the satellite. The user beam adapts to the user's location and co-channel interference environment.
