A new effective method and its two modifications for solv- ing Hermitian pentadiagonal block circulant systems of linear equations are proposed. New algorithms based on the proposed method are con- structed. Our algorithms are then compared with some classical tech- niques as far as implementation time is concerned, number of operations and storage. Numerical experiments corroborating the effectiveness of the proposed algorithms are also reported.
