Super-Orthogonal Block Codes with Multichannel Equalisation and OFDM in Frequency Selective Fading
EURASIP Journal on Wireless Communications and Networking, 2010 Super-orthogonal block codes in space-time domain (i.e., Super-orthogonal space-time trellis codes (SOSTTCs)) were initially designed for frequency nonselective (FNS) channels but in frequency selective (FS) channels these super-orthogonal block codes ...

Space-Time Block Coded Cooperative MIMO Systems [PDF]
Sensors, 2020 The main objective of a Cooperative Multiple-Input Multiple-Output (CMIMO) system is to improve network throughput and network coverage and save energy. By grouping wireless devices as virtual multi-antenna nodes, it can thus simulate the functions of multi-antenna systems. A Space-Time Block Code (STBC) was proposed to utilize the spatial diversity of

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.

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

Distributed space-time block codes [PDF]
, 2011 Introduction In this chapter, we consider space-time coding strategies for multiple-relay cooperative systems that effectively harness available spatial diversity. More specifically, the goal is to examine ways to forward signals efficiently from multiple relays to the destination while addressing the important practical issue of synchronization ...

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 ...

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 ...
