On permutation of space‐time‐frequency block codings

open access: yesIET Communications, 2014
Multi‐input multi‐output‐orthogonal frequency‐division multiplexing is the foundation of next generation of wireless communication systems and space‐time‐frequency block coding (STFBC) is considered one of the best schemes for implementing these systems. STFBCs have very complex structures and many parameters affect their performance.

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

open access: yes, 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 ...

KOMBINASI ORTHOGONAL SPACE TIME BLOCK CODING DAN BLOCK CHANNEL CODING UNTUK MENINGKATKAN KINERJA SISTEM ORTHOGONAL FREQUENCY DIVISION MULTIPLEXING

open access: yesTeknologi dan Kejuruan, 2012
It is well known that space-time diversity using space-time coding (STC) is an effective technique to improve wireless communication performance. STC was designed for flat fading channel and consist of space-time trellis code (STTC) and space-time block ...

Optimized Distributed Generalized Reed-Solomon Coding with Space-Time Block Coded Spatial Modulation

open access: yesSensors, 2022
We present a well-known generalized Reed–Solomon (GRS) code incorporated with space-time block coded spatial modulation (STBC-SM) for wireless networks, which is capable of enjoying coded cooperation between the source and the relay.

Space-time block coding for spatial modulation

open access: yes21st 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 ...

Near-capacity cooperative space-time coding employing irregular design and successive relaying [PDF]

open access: yes, 2010
In this paper, we develop a capacity-approaching Cooperative Space-Time Coding CSTC scheme employing irregular design for a twin-relay aided network as an extension of our previous work cast in the context of a half-duplex single-relay-aided network. For

Capacity Analysis of Channel Inversion Using Space-Time Block Coding with Transmit Power Control

open access: yesElektronika ir Elektrotechnika, 2022
In this paper, we analyze channel inversion with transmit diversity in terms of capacity and bit error rates in correlated fading. We obtain the Shannon capacity of Rayleigh fading channel under channel inversion using spatially correlated dual branch ...
