On Jacobi-type methods for blind equalization of paraunitary channels

摘要

In this paper a study of the cumulant-based blind equalization algorithms PAJOD and PAFA is conducted. Both algorithms assume that the data have been pre-whitened and hence the problem reduces to the estimation of paraunitary channels. The main contribution of this paper is an efficient implementation of the PAJOD algorithm called PAJ0D2. Second, a performance comparison between the PAJOD, PAJ0D2 and PAFA algorithms is reported.
