, 2013 —Successive-relaying-aided (SR) cooperative multi-carrier (MC) space–time shift keying (STSK) is proposed for frequency-selective channels. We invoke SR to mitigate the typical 50% throughput loss of conventional half-duplex relaying schemes and MC code ...

Multi-Set Space-Time Shift Keying Assisted Adaptive Inter-Layer FEC for Wireless Video Streaming
IEEE Access, 2019 The scalable video coding extension of H.265/high efficiency video coding is capable of supporting diverse video resolutions. Due to the fact that the enhancement layer (EL) is encoded and decoded with the aid of the base layer (BL), the decodability of ...

Radio Over Fiber Downlink Design for Spatial Modulation and Multi-Set Space-Time Shift-Keying
IEEE Access, 2018 Spatial modulation (SM) and multi-set space-time shift-keying (MS-STSK) are capable of striking a flexible design trade-off between the multiplexing and diversity gains attained.

Space-time coded systems with continuous phase frequency shift keying [PDF]
GLOBECOM '05. IEEE Global Telecommunications Conference, 2005., 2005 A space-time (ST) trellis encoded scheme with M-ary continuous phase frequency shift keying with a modulation index of 1/M (M-CPFSK) is presented. A ST-M-CPFSK system model that incorporates the Rimoldi decomposition of CPFSK is developed. The Rimoldi decomposition separates the non-memory component of CPFSK from the memory component. The latter can be

Adaptive
IEEE Access, 2020 Due to high peak-to-average-power ratio (PAPR) and low spectral-efficiency, the conventional Fast Fourier Transform based orthogonal frequency division multiplexing (OFDM) is losing its place to the other multicarrier modulation schemes.

A novel space-time shift keying and its reduced complexity detector [PDF]
2012 8th International Wireless Communications and Mobile Computing Conference (IWCMC), 2012 This paper proposes a space-time shift keying (STSK) modulation scheme, which maps the information onto two dimensions, i.e., the temporal and spatial dimensions. For the proposed modulation, a detector with reduced complexity is also proposed. The complexity of proposed detector is reduced with the slight degradation of performance.

New super-orthogonal space-time trellis codes using differential M-PSK for noncoherent mobile communication systems with two transmit antennas [PDF]
, 2010 In this paper, we develop super-orthogonal space-time trellis codes (SOSTTCs) using differential binary phase-shift keying, quadriphase-shift keying and eight-phase shift keying for noncoherent communication systems with two transmit antennas without ...
