Transmit Diversity Assisted Space Shift Keying for Colocated and Distributed/Cooperative MIMO Elements [PDF]
Space Shift Keying (SSK) modulation is a recently proposed MIMO technique, which activates only a single transmit antenna during each time slot and uses the specific index of the activated transmit antenna to implicitly convey information.

Analysis of transmit-receive diversity in Rayleigh fading [PDF]
We analyze the error performance of a wireless communication system employing transmit-receive diversity in Rayleigh fading. By focusing on the complex Gaussian statistics of the independent and identically distributed entries of the channel matrix, we derive a formula for the characteristic function (c.f.) of the maximum output signal-to-noise ratio ...

Optimal training sequences for channel estimation in cyclic-prefix-based single-carrier systems with transmit diversity [PDF]
In this paper, we investigate a new class of training sequences that are optimal for least squares (LS) channel estimation in systems employing transmit diversity and single-carrier (SC) modulation with a cyclic prefix (CP) extension.

Super-Orthogonal Space-Time Turbo Transmit Diversity for CDMA
Studies have shown that transmit and receive diversity employing a combination of multiple transmit-receive antennas (given ideal channel state information (CSI) and independent fading between antenna pairs) will potentially yield maximum achievable ...

A modified Alamouti scheme for frequency selective channels incorporating turbo equalization [PDF]
The Alamouti scheme can achieve transmit diversity in the presence of frequency selective flat fading channels. The technique has received considerable attention mainly because of its processing simplicity. Recently, a modification to the Alamouti scheme

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 ...

A Joint Precoding Scheme and Selective Transmit Diversity [PDF]
We propose the use of the precoding (PC) scheme, which can be used to combat both the Multiple Access Interference (MAI) and Inter-Path Interference (IPI), combined with the Selective Transmit Diversity (STD) for high data rate transmissions. The proposed scheme is considered over frequency selective Rayleigh fading channels jointly with a RAKE in the ...

Evaluating existing set-top boxes versus transmit diversity schemes
Transmit diversity is a technique that exploits the nature of fading due to multipaths and that potentially incurs delay and pre- and post-echoes into the received signals.

Differential Space-Time Spreading using Four Transmit Antennas and Iteratively Detected Sphere Packing Modulation [PDF]
This paper presents a novel Differentially encoded Space-Time Spreading (DSTS) scheme using four transmit antennas that can be readily combined with PSK, QAM, as well as Sphere Packing (SP) modulation schemes.
