| Abstract | An extension of complex proportionate-type normalized least mean square algorithms is proposed and derived. This new algorithm called the complex proportionate-type affine projection algorithm helps the estimation of unknown impulse responses when the input signal is colored. The derivation of the complex proportionate-type affine projection algorithm is performed by minimizing the second norm of the weighted difference between the current estimate of the impulse response and the estimate at the next time step under constraints that multiple a posteriori output errors are zero. Several variants of the algorithm are obtained as in the case of the complex proportionate-type normalized least mean square algorithm. It is shown how to use the algorithm in the case of widely linear systems. The learning curves of the algorithms are compared for several standard gain assignment laws for colored and speech input. Through simulation it was demonstrated that the complex proportionate-type affine projection algorithm offers superior convergence performance for colored input signals relative to complex proportionate-type normalized least mean square algorithms and that using separate gains to update the real and imaginary parts of the estimated impulse response, as opposed to the same gain, improves the convergence performance. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
