¡°The main challenges come from the strong coupling among base station beamforming, artificial noise, and STAR-RIS coefficients. In addition, unit-modulus constraints and SIC conditions further complicate the problem. Conventional optimization techniques usually result in high computational complexity and are difficult to scale, especially for large STAR-RIS systems.¡±
