Tight frames, also known as general Welch-bound-equality sequences, generalize
orthonormal systems. Numerous applications-including communications, coding, and …

Industrial automation and safety applications demand low latency and ultra reliable
communication. Currently deployed wireless communication technologies are mostly …

This paper considers the design of both a transmitter and a receiver for noncoherent
communication over a frequency-flat, richly scattered multiple-input multiple-output (MIMO) …

In this paper, we propose a practical structured constellation for non-coherent
communication with a single transmit antenna over Rayleigh flat and block fading channel …

We construct a new family of space-time codes suited for multiple-antenna non-coherent
communications over Rayleigh flat fading channels. These codes use all the complex …

We construct unitary noncoherent space-time constellations, which can be considered as a
concatenation of a training block with an orthogonal design. With a simple construction, our …

In practical applications, such as direct spread code division multiple access
communications, space-time codes and compressed sensing, and codebooks with small …

The bit-error rate (BER) performance of orthogonal space-time block codes (STBCs) in
correlated multiple-input multiple-output (MIMO) channels is studied. We first derive closed …

The construction of highly incoherent frames, sequences of vectors placed on the unit hyper
sphere of a finite dimensional Hilbert space with low correlation between them, has proven …

Recently, the use of coherent space-frequency coding in orthogonal frequency-division
multiplexing (OFDM)-based frequency-selective multiple-input multiple-output (MIMO) fading …
