The optimization engine is required to handle simultaneously multiple objective functions and multiple arbitrary equality and inequality constraints. Moreover, it is required to handle not only infinite-precision optimization, but also finite-precision optimization over the canonical signed-digit transfer function coefficient space. In addition, it is required to have guaranteed convergence, i.e. it is required to find a solution if one exists. The Papillon DSP OptiStation environment is based on a multi-threaded multi-process architecture facilitating co-operative online interaction between the user on the one hand and the optimizer on the other, through a Tcl/Tk graphical user interface. It is required that the user be able to change, interactively, any time-domain and/or frequency domain design specifications throughout the course of the optimization.","PeriodicalId":424855,"journal":{"name":"1998 IEEE Symposium on Advances in Digital Filtering and Signal Processing.

In this method, the digital filter is implemented as a cascade arrangement of 2nd-order sections. The first section is designed through optimization techniques so as to satisfy as far as possible the overall required specifications. A second section is then added which is designed through optimization techniques so that the first two sections satisfy as far as possible the overall required specifications. This process is repeated until a multisection filter is obtained which satisfies the required specifications under the most critical circumstances imposed by the application at hand. The minimum number of sections required to process a particular input signal can then by switched on through the use of a simple adaptation mechanism and, in this way, the power consumption can be minimized. This design structure is achieved by formulating the design on the kth section as a weighted quadratic programming problem with stability, amplitude response, and the first k-1 sections as constraints.","PeriodicalId":424855,"journal":{"name":"1998 IEEE Symposium on Advances in Digital Filtering and Signal Processing.

The main application emphasis is oriented to echo cancellation but other areas of adaptive signal processing can be included, as for example postcursor filter in decision feedback equalization. The particular realization proposed is based on an orthonormal family of functions, that has as special cases the Laguerre functions and the Kautz functions. Except for the lattice realization, that is based on the nice properties of Szego orthonormal polynomials, no other adaptive IIR filter realization using orthonormal characteristics seems to be extensively studied in the literature. In spite of the fact that the proposed realization has manifolds, it is demonstrated that they are not an important drawback for convergence speed as for example in the parallel or cascade adaptive IIR realizations. A set of computer simulations to illustrate the comparison between the IIR adaptive filter structure proposed and an adaptive FIR filter structure based on a truncated Laguerre orthonormal realization is presented. In this comparison the relevant aspects studied were computational complexity, modeling capability and reduced order performance.","PeriodicalId":424855,"journal":{"name":"1998 IEEE Symposium on Advances in Digital Filtering and Signal Processing.
