Complex Quadrature Spatial Modulation
scheme referred to as complex quadrature spatial modulation (CQSM). In contrast to quadrature spatial modulation (QSM), CQSM transmits two complex signal constellation symbols on the real and quadrature spatial dimensions at each channel use, increasing the spectral efficiency. To this end, signal symbols transmitted at any given time instant are drawn from two different modulation sets. The fi...
متن کاملLow-Complexity Detection Scheme for Generalized Spatial Modulation
Abstract—Generalized spatial modulation was recently proposed, in which only part of the transmit antennas are activated to send the same complex symbol. Compared to Spatial Modulation (SM), it can offer spatial diversity. Moreover, it is no longer limited to the number of the transmit antennas. In this letter, a low complexity detection scheme is presented, which can achieve a near Maximum-Li...
متن کاملLow-complexity detection of quadrature spatial modulation
ELECT Quadrature spatial modulation (QSM) is a recently proposed multipleinput multiple-output transmission scheme which improves the spectral efficiency of classical spatial modulation (SM) by increasing the number of information bits transmitted by antenna indices. In QSM, a complex data symbol is decomposed into its real and imaginary components; then, these two components are independently ...
متن کاملA Generalized Grouping and Retrieval Scheme for Stored MPEG Video
MPEG, in addition to being an international standard, is currently the most popular coding scheme for stored video. For several applications that require stored video, such as video-on-demand, it is advantageous to group MPEG frames into segments. Retrieving segments instead of individual frames can result in a more eecient use of disk retrieval resources and consequently, in the support of a l...
متن کاملCooperative Amplify-and-Forward Relaying Systems with Quadrature Spatial Modulation
Quadrature spatial modulation (QSM) is a recent digital multiple-input multiple-output (MIMO) transmission technique. Combined with cooperative relaying, QSM improves the overall spectral efficiency and enhances the communication reliability. In this paper, we study the performance of QSM amplify-and forward cooperative relaying systems. In particular, a closed-form expression for the average p...
