On the amicability of orthogonal designs

Journal of Combinatorial Designs, 2009
AbstractAlthough it is known that the maximum number of variables in two amicable orthogonal designs of order 2np, where p is an odd integer, never exceeds 2n+2, not much is known about the existence of amicable orthogonal designs lacking zero entries that have 2n+2 variables in total.

On the Design of Massive Non-Orthogonal Multiple Access With Imperfect Successive Interference Cancellation

IEEE Transactions on Communications, 2019
In this paper, we address a practical but adverse problem that successive interference cancellation (SIC) is imperfect in a massive non-orthogonal multiple access (NOMA) system.

Using Orthogonal and Quasi-Orthogonal Designs in Wireless Relay Networks

IEEE Transactions on Information Theory, 2007
Distributed space-time coding was proposed to achieve cooperative diversity in wireless relay networks without channel information at the relays. Using this scheme, antennas of the distributive relays work as transmit antennas of the sender and generate a space-time code at the receiver.

Orthogonal designs of Kharaghani type. I.

Ars Comb., 2003
Summary: We use an array constructed by \textit{H. Kharaghani} [J. Comb. Des. 8, 166-173 (2000; Zbl 0985.05015)] to obtain infinite families of 8-variable Kharaghani type orthogonal designs, \(OD(8t;k_1,k_1,k_1,k_1,k_2,k_2,k_2,k_2)\), where \(k_1\) and \(k_2\) must be sums of two squares.

Orthogonal designs in powers of two

1977
Repeat designs are introduced and it is shown how they may be used to give very powerful constructions for orthogonal designs in powers of two. These results are used to show all full four variable and all three variable designs exist in 2t , t ≤ 9. We believe these constructions demonstrate the existence of all possible four variable designs with no
