Key Points

To develop a real-time adaptive sensor array processing algorithm capable of preserving signals from a specified direction while suppressing interference from other directions without a priori statistical knowledge.
Derived a constrained least-mean-squares formulation that enforces linear equality constraints on adjustable sensor tap weights.
Conducted mathematical analysis and computer simulations to test weight adaptation and output noise power minimization.
Used a geometric model to evaluate constraint preservation and quantify the accumulation of digital quantization errors.
Iterative weight adaptation successfully minimized output noise power while strictly preserving the selected frequency response along the target direction.
Geometric analysis confirmed that the algorithm prevents the gradual accumulation of quantization errors during digital hardware implementation.
