Implication

Simulation study reveals enhanced target angle estimation in multi-user wireless networks, indicating mutual information optimization effectively suppresses communication interference.

Key Points

Design MIMO integrated sensing and communication beamforming strategies that maximize target echo mutual information while satisfying individual communication data rate requirements.
Modeled single-user ISAC scenarios across three interference profiles (none, point, and extended) alongside a multi-user extended interference scenario.
Developed optimization algorithms using closed-form solutions, semidefinite relaxation (SDR), and Majorization-Minimization (MM) combined with successive convex approximation (SCA).
Yielded superior transmit beampatterns and lower angle estimation root mean square error (RMSE) relative to conventional Cramér-Rao bound and beampattern benchmarks.
Suppressed user-induced echo interference effectively across both single-user and multi-user operating regimes without compromising communication data rate thresholds.
