Multiple-Symbol Differential Sphere Detection Aided Differential Space-Time Block Codes Using QAM Constellations [PDF]

, 2011
We propose Multiple-Symbol Differential Detection (MSDD) aided Differential Space-Time Block Codes (DSTBCs) using QAM. Our solution eliminates the requirement of high-complexity MIMO channel estimation and its pilot overhead, while mitigating the ...

Performance Evaluation of Spatial Modulation and QOSTBC for MIMO Systems

EAI Endorsed Transactions on Mobile Communications and Applications, 2015
Multiple-input multiple-output (MIMO) systems require simplified architectures that can maximize design parameters without sacrificing system performance. Such architectures may be used in a transmitter or a receiver.

Equivalent-Capacity-Based Design of Space-Time Block-Coded Sphere-Packing-Aided Multilevel Coding [PDF]

, 2007
A multilevel coding (MLC) scheme invoking sphere packing (SP) modulation combined with space time block coding (STBC) is designed. The coding rates of each of the MLC component codes are determined using the so-called equivalent capacity based ...

Quantum Codes in Classical Communication: A Space-Time Block Code From Quantum Error Correction

IEEE Open Journal of the Communications Society, 2021
We propose a general framework for noncoherent communication using techniques from the field of quantum error correction (QEC). We first propose an approach for analyzing a classical communication channel as a quantum channel, and develop an extension of

Pragmatic Space-Time Codes for Cooperative Relaying in Block Fading Channels

EURASIP Journal on Advances in Signal Processing, 2008
We address the problem of construction of space-time codes for cooperative communications in block fading channels. More precisely, we consider a pragmatic approach based on the concatenation of convolutional codes and BPSK/QPSK modulation to obtain ...

Space-time block coding for spatial modulation

21st Annual IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, 2010
Space-time block coded spatial modulation (STBC-SM), which employs space-time block coding (STBC) for spatial modulation (SM), is proposed as a new multiple-input multiple-output (MIMO) transmission scheme. In the STBC-SM scheme, the transmitted information symbols are expanded not only to the space and time domains but also to the spatial (antenna ...

Performance Analysis of Space-Time Block Codes in Flat Fading MIMO Channels with Offsets

EURASIP Journal on Wireless Communications and Networking, 2007
We consider the effect of imperfect carrier offset compensation on the performance of space-time block codes. The symbol error rate (SER) for orthogonal space-time block code (OSTBC) is derived here by taking into account the carrier offset and the ...
