In a global world, the human population invariably increases while resources gradually
decrease as cities and towns constantly consume resources to satisfy their needs and …

It is shown why the discriminant of a maximal order within a cyclic division algebra must be
minimized in order to get the densest possible matrix lattices with a prescribed nonvanishing …

Multiple-input double-output (MIDO) codes are important in the near-future wireless
communications, where the portable end-user device is physically small and will typically …

In this paper, a new method is proposed to obtain full-diversity, rate-2 (rate of two complex
symbols per channel use) space-time block codes (STBCs) that are full-rate for multiple …

This paper addresses the question of achieving capacity with lattice codes in multi-antenna
block fading channels when the number of fading blocks tends to infinity. A design criterion …

Multiple-input double-output (MIDO) codes are important in future wireless communications,
where the portable end-user device is physically small and uses only two receive antennas …

The goal of this paper is to design fast-decodable space-time codes for four transmit and two
receive antennas. The previous attempts to build such codes have resulted in codes that are …

In this work we extend the Construction A lattices proposed in 1, to Hurwitz quaternion
integers. This construction is provided by using an isomorphism from a version of the …

For an nt transmit, nr receive antenna system (nt× nr system), a full-rate space time block
code (STBC) transmits at least nmin= min (nt, nr) complex symbols per channel use. The …

An equivalent model for a multiple-input-multiple-output communication system with space-
time block codes (STBCs) is proposed based on a revealed connection between STBCs and …
