Confidence regions based on the linearization method (black ellipse) and the likelihood method (filled dots). The estimated parameters are denoted by a cross and the true parameters by a circle. (a) Single-path channel at 10 dB. (b) Single-path channel at 30 dB. (c) Single-path channel at 50 dB. (d) Two-path channel at 10 dB. (e) Two-path channel at 30 dB. (f) Two-path channel at 50 dB.
