Abstract
The interference suppression (IS) capability of a frequency hopping spread spectrum communication system can be increased by using additional IS algorithms. In this paper a new interference suppression algorithm called short overlapping singular value decomposition (SOSVD) is described. Many of the existing blind IS algorithms perform unsatisfactorily when interference is wideband. It is shown by simulations that the performance of the proposed SOSVD method clearly exceeds the performance of the blind recursive least squares (RLS) directed interpolation filter in a wideband interference environment. The computational complexity of the proposed method is tolerable because the size of the SVD input matrix is small and constant.
