Coherent Code Tracking for Spatial Transmit Diversity DS-CDMA Systems
Spatial transmit diversity schemes are now well integrated into third-generation cellular mobile communication system specifications. When DS-CDMA-based technology is deployed in typical macro- and microcell environments, multipath diversity and spatial ...

Repeated MCIK-OFDM With Enhanced Transmit Diversity Under CSI Uncertainty
This paper investigates the opportunity for a repetition coded multi-carrier index keying—orthogonal frequency division multiplexing (MCIK-OFDM), termed repeated MCIK-OFDM (ReMO), which can provide superior performance over existing schemes at the same ...

On the Role of Transmit Correlation Diversity in Multiuser MIMO Systems [PDF]
Correlation across transmit antennas in multiple-input multiple-output (MIMO) systems has been studied in various scenarios and has been shown to be detrimental or provide benefits depending on the particular system and underlying assumptions.

On the Capacity of Certain Space-Time Coding Schemes
We take a capacity view of a number of different space-time coding (STC) schemes. While the Shannon capacity of multiple-input multiple-output (MIMO) channels has been known for a number of years now, the attainment of these capacities remains a ...

Constellation Randomization Achieves Transmit Diversity for Single-RF Spatial Modulation
The performance of spatial modulation (SM) is known to be dominated by the minimum Euclidean distance (MED) in the received SM constellation. In this paper, a symbol-scaling technique is proposed for SM in the multiple-input-multiple-output (MIMO ...

Compressed Sensing Improves the Performance of Subcarrier Index-Modulation-Assisted OFDM
In orthogonal frequency division multiplexing relying on subcarrier index modulation (OFDM-SIM), the information is conveyed by both the indices of the activated subcarriers and the conventional amplitude-phase modulated (APM) symbols.

Transmit diversity code filter sets (TDCFSs) are a method of predistorting the common waveforms from multiple transmitters in the same frequency channel, as in a single frequency network, in order to minimize the possibility of cross-interference among ...
