Orthogonal orthogonal overcomplete kernel design for sparse representation
2012 8th International Symposium on Communication Systems, Networks & Digital Signal Processing (CSNDSP), 2012This paper proposes an optimal orthogonal overcomplete kernel design for sparse representation such that the sum of the L 1 norms of a set of transformed vectors is minimized. When there is only one training vector in the set, both the optimal transformed vector and the optimal orthogonal kernel are derived analytically.

Space-time diversity using orthogonal and amicable orthogonal designs
2000 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.00CH37100), 2001We consider the utilization of multiple transmitter and receiver antennas for space-time diversity. The optimal SNR scheme, which also provides the best diversity, is outlined. This scheme however involves a reduction in the data rate. Coding schemes are then presented which not only achieve the optimal SNR but also mitigate the reduction of data rate.

Novel construction methods of quaternion orthogonal designs based on complex orthogonal designs
2017 IEEE International Symposium on Information Theory (ISIT), 2017Quaternion orthogonal designs (QODs) are considered the foundation of orthogonal space time polarization block codes (OSTPBCs). OSTPBCs benefit from orthogonal polarizations and orthogonal space and time block coding simultaneously to enhance the capacity of wireless communication systems. To exploit these advantages of OSTPBCs, this paper explores two

Orthogonal designs with maximal rates
IEEE Transactions on Information Theory, 2003Orthogonal designs have been used as space-time block codes for wireless communications with multiple transmit antennas, which can achieve full transmit diversity and have a very simple decoupled maximum-likelihood decoding algorithm. The rate of an orthogonal design is defined as the ratio of the number of transmitted information symbols in a block of

Design of lapped orthogonal transforms
IEEE Transactions on Image Processing, 1996We investigate the design of lapped orthogonal transforms for data compression of images. We present some properties and new results of paraunitary filter banks. We concentrate on the case where the filter length L=2K, where K is the number of channels.

Orthogonal and nearly orthogonal designs for computer experiments
Biometrika, 2009We introduce a method for constructing a rich class of designs that are suitable for use in computer experiments. The designs include Latin hypercube designs and two-level fractional factorial designs as special cases and fill the vast vacuum between these two familiar classes of designs.
