... (9) Here S(k )and are referred to as the linear and nonlinear parameters, respectively, since the noise corrupted data X(k) is linear in S(k) but nonlinear in Θ. A standard procedure of solving this ... signal parameters and noise pa- rameters are interrelated. We approach this problem by first fixing Θ and S in (15) and deriving an estimator of q as a function of Θ and S. After...
