The first performance measure (SNRE).
| |||||||||||||||||||||||||||||||||||||||||||||||||
The multichannel blind deconvolution (MBD) technique was applied by using the conventional method (FIR-2 model with two orders and FIR-4 model with 4 orders) and the proposed method (OU model or stochastic calculus). We compared between these methods by using performance measure SNRE (3.1) at variant noise. is the signal to noise ratio of the estimate of Aortic AP with free noise. SNRE0.012 is the signal to noise ratio of the estimate with noise variance = 0.012, with noise variance = 0.024, and so forth. |
