Adaptive generalized space shift keying
In this article, we propose a closed-loop precoding method for the Generalized Space Shift Keying (GSSK) modulation scheme, suitable for Multiple-Input-Single-Output (MISO) systems and denoted as adaptive GSSK (AGSSK), which achieves transmit-diversity gains in contrast to GSSK. For the case of a perfect feedback channel, we analytically show that for three and four antennas at the transmitter ...
متن کاملUnified MIMO-Multicarrier Designs: A Space-Time Shift Keying Approach
A survey and tutorial is provided on the subject of multiple-input–multiple-output (MIMO) multicarrier (MC) systems relying on the space–time shift keying (STSK) concept. We commence with a brief review of the family of MIMO systems, which is followed by the design of STSK systems in the context of MC modulation-based transmissions over dispersive wireless channels. Specifically, the STSK schem...
متن کاملSpace-Time Hyper Phase Shift Keying Over Fading Channels
The emerging need for high data rate and coding gain has raised considerable interest in coded modulation schemes. Trellis coded modulation (TCM) is a bandwidth efficient transmission scheme that can achieves high coding gain by integrating coding and modulation. Space-time trellis coding combines channel coding with multiple transmit and multiple receive antennas to achieve bandwidth and power...
متن کاملAn optimum hardware detector for constant envelope quadrature-quadrature phase-shift keying (CEQ2PSK)
A hardware detector for constant envelope quadrature-quadrature phase-shift keying (CEQPSK) is proposed. It uses appropriate hard decisions; yet, it achieves optimum probability of bit error performance, unlike the suboptimum detector of Saha and Birdsall. This optimum performance is verified through Monte Carlo computer simulations. Additionally, a more correct expression is given for the prob...
متن کاملStructured Dispersion Matrices from Space-Time Block Codes for Space-Time Shift Keying
Coherent Space-Time Shift Keying (CSTSK) is a recently developed generalized shift-keying framework for Multiple-Input Multiple-Output systems, which uses a set of Space-Time matrices termed as Dispersion Matrices (DM). CSTSK may be combined with a classic signaling set (eg. QAM, PSK) in order to strike a flexible tradeoff between the achievable diversity and multiplexing gain. One of the key b...
