Orthogonal moments are recognized as useful tools for object representation and image analysis. It has been shown that the recently developed discrete orthogonal moments have better performance than the conventional continuous orthogonal moments. In this paper, a new set of discrete orthogonal polynomials, namely Hahn polynomials, are introduced. The related Hahn moment functions defined on thi...

Abstract This communication suggests an orthogonal interleaver set for interleave division multiple access (IDMA) based non (NOMA) schemes from beyond 5G viewpoint to support enormous increase in user count. The method generates by providing two mother interleavers as seed generate other users’ interleaving patterns progressively. key feature of the proposed scheme is that it reduces implementa...

Abshacl This paper proposes , B novel orthogonal hop set partitioning (OHSP) scheme aimed at reducing the collisions between piconets at the hop level, by pariitioning the original Bluetooth hop band into five orthogonal sub-hop sets. To support OHSP, an orthogonal hop sets construction method and enhanced synthesizer structure are presented. In each piconet, the master randomly and independent...

An approach is proposed which, given a family of linearly independent functions, constructs the appropriate bi-orthogonal set so as to represent the orthogonal projector operator onto the corresponding subspace. The procedure evolves iteratively and it is endowed with the following properties: i) it yields the desired bi-orthogonal functions avoiding the need of inverse operations ii) it allows...

in this paper, we propose space-time block codes based on constituent intersectant orthogonal designs. after channel model is formulated, we studied the space-time block codes from constituent intersectant orthogonal designs. at last we made simulations for the space-time block codes from complex orthogonal design and the space-time block codes from constituent intersectant orthogonal design to...
