Differential Space Time Shift Keying for Dispersive Multi-user Scenarios using OFDM
Spatial modulation (SM) is a recently developed transmission technique that uses multiple antennas. The concept of SM is extended to both the space and time dimensions to provide a general shift-keying framework. A new modulation scheme called Differential STSK (DSTSK) scheme, assisted by the Cayley unitary transform is proposed to OFDM aided Multiple Input Multiple Output (MIMO) Communication ...
متن کاملM-ary amplitude shift keying OFDM system
Coherent M-ary ASK is proposed to be used in OFDM systems. The frequency separation between subcarriers is only 1/2T instead of 1/T. With a slightly wider bandwidth, an M -ary ASK-OFDM can achieve the same BER of M-ary QAM-OFDM and a better BER than that of MPSK-OFDM. The M -ary ASK-OFDM has the same Peak-To-Average-Power Ratio (PAPR) as that of the M-ary QAM-OFDM. The MASKOFDM can be implement...
متن کاملAdaptive 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 کاملSpace Shift Keying Modulation for MIMO Systems
In this seminar, we introduce a modulation scheme, termed space shift keying (SSK), suitable for multiple-input multiple-output (MIMO) systems. SSK modulation, which is a fundamental component of spatial modulation, inherently exploits fading in wireless communications to provide better performance over conventional amplitude/phase modulation (APM) techniques. In SSK, only the antenna indices, ...
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...
