Algebraic Cayley Differential Space–Time Codes [PDF]
IEEE Transactions on Information Theory, 2007 Cayley space-time codes have been proposed as a solution for coding over noncoherent differential multiple-input multiple-output (MIMO) channels. Based on the Cayley transform that maps the space of Hermitian matrices to the manifold of unitary matrices, Cayley codes are particularly suitable for high data rate, since they have an easy encoding and can

Cayley differential unitary space-time codes [PDF]
IEEE Transactions on Information Theory, 2002 Summary: One method for communicating with multiple antennas is to encode the transmitted data differentially using unitary matrices at the transmitter, and to decode differentially without knowing the channel coefficients at the receiver. Since channel knowledge is not required at the receiver, differential schemes are ideal for use on wireless links ...

Artificially Time-Varying Differential MIMO for Achieving Practical Physical Layer Security
IEEE Open Journal of the Communications Society, 2021 In this paper, we propose a differential multiple-input multiple-output (MIMO) scheme based on the novel concept of chaos-based time-varying unitary matrices to demonstrate—for the first time in the literature—the ability of differential ...

Differential distributed space-time coding with imperfect synchronization [PDF]
2014 IEEE Global Communications Conference, 2014 Differential distributed space-time coding (D-DSTC) has been considered to improve both diversity and data-rate in cooperative communications in the absence of channel information. However, conventionally, it is assumed that relays are perfectly synchronized in the symbol level.

EURASIP Journal on Wireless Communications and Networking, 2007 We report a simple differential modulation scheme for quasi-orthogonal space-time block codes. A new class of quasi-orthogonal coding structures that can provide partial transmit diversity is presented for various numbers of transmit antennas ...

Double-differential coding for orthogonal space-time block codes [PDF]
2008 IEEE International Conference on Acoustics, Speech and Signal Processing, 2008 Communications over multiple-input multiple- output (MIMO) channels with carrier offsets is an important practical and theoretical problem. Double-differential coding is a technique, which allows the receiver to decode the data without any channel or carrier offset knowledge.
