Abstract :
It is shown that the quadratic constraint established by M.H. Er and A. Canton: (see IEEE J. Oceanic Eng., vol.OE-10, p.231-40), can be approximated using linear and quadratic constraints. Based on the latter set of constraints, the equivalence between the MMSE (minimum mean square error) and CCMP (correlation-constrained minimization of power) methods for broadband and robust antenna-array design is further established. The relationship provides several insights into the CCMP and its improved methods
