Channel Parameters and Performance Specifications
The channel impulse responses and noise levels used in each example are
listed below. The locations of CMA minima, their respective costs,
and the resulting channel-equalizer impulse responses are also included.
Well-Behaved Channel, No Noise
- channel: [0.2, 0.5, 1, -0.1]
- CMA minima of cost 0 at +/-[1.92, 0.19]
yielding cascaded response +/-[1,0]
- CMA minima of cost 0 at +/-[0.38, 0.96]
yielding cascaded response +/-[0,1]
Channel with Nearly-Reflected Roots, No Noise
- channel: [0.01, 1, 0.01,-1]
- CMA minima of cost 0 at +/-[0.50, 50]
yielding cascaded response +/-[1,0]
- CMA minima of cost 0 at +/-[-0.50, 50]
yielding cascaded response +/-[0,1]
Well-Behaved Channel, 7dB SNR
- channel: [0.2, 0.5, 1, -0.1]
- CMA minima of cost 0.57 at +/-[0.93, 0.14]
yielding cascaded response
+/-[0.49,0.04]
- CMA minima of cost 0.39 at +/-[-0.19, 0.69]
yielding cascaded response
+/-[0.04,0.71]
Channel with Nearly-Reflected Roots, 7dB SNR
- channel: [0.01, 1, 0.01,-1]
- CMA minima of cost 0.45 at +/-[0.45, 0.00]
yielding cascaded response
+/-[0.45,-0.45]
Undermodelled (though well-behaved) Channel, No Noise
- channel: [0.1, 0.3, 1.0, -0.1, -0.5, 0.2]
- CMA minima of cost 0.49 at +/-[1.85, 0.11]
yielding cascaded response
+/-[0.57, -0.07, 0.43]
- CMA minima of cost 0.26 at +/-[-0.79, 0.73]
yielding cascaded response
+/-[-0.16, 0.81, 0.21]
