Abstract:International audienceWe consider the design of a pair of time-domain filters to achieve target signal cancelation in a multi-source envi-ronment. The problem is formulated as a minimization of a sum squared error cost function with respect to the pair of finite impulse response cancelation filters. Direct mini-mization is achieved through an alternating gradient descent based method, whereas a novel method based on the method of principal angles is proposed which exploits the singular value decomposition.
