Layered Space-Time Index Coding [PDF]

open access: greenIEEE Transactions on Information Theory, 2017
Multicasting $K$ independent messages via multiple-input multiple-output (MIMO) channels to multiple users where each user already has a subset of messages as side information is studied. A general framework of constructing layered space-time index coding (LSTIC) from a large class of space-time block codes (STBC), including perfect STBC, is proposed ...

Aligned Space Time Block Codes for the 2-User X Channel with Secrecy Constraints

open access: yesInternational Journal of Antennas and Propagation, 2015
Interference alignment (IA) is a technique used to reduce the dimension of the interference, where consequently the multiplexing rate is increased. In the 2-user X channel, combining IA with space-time block codes increases the diversity gain.

Performance of Antenna Diversity with Turbo Trellis Coded Modulation Over Nakagami Channels

open access: yesElectrica, 2019
In this paper, we will use the Space Time Block codes for antenna diversity, and the performance of Space-Time – Turbo Trellis Coded Modulation (ST-TTCM) is investigated over Nakagami channels.

Optimal space-time codes for the MIMO amplify-and-forward cooperative channel

open access: yes, 2006
In this work, we extend the non-orthogonal amplify-and-forward (NAF) cooperative diversity scheme to the MIMO channel. A family of space-time block codes for a half-duplex MIMO NAF fading cooperative channel with N relays is constructed.

The DMT classification of real and quaternionic lattice codes

open access: yes, 2018
In this paper we consider space-time codes where the code-words are restricted to either real or quaternion matrices. We prove two separate diversity-multiplexing gain trade-off (DMT) upper bounds for such codes and provide a criterion for a lattice code

Space-Time Turbo Coded Modulation: Design and Applications

open access: yesEURASIP Journal on Advances in Signal Processing, 2002
A design method for recursive space-time trellis codes and parallel-concatenated space-time turbo coded modulation is proposed that can be applied to an arbitrary existing space-time trellis code.

Turbo detection-decoding method for bit-interleavered random layered space-time codes

open access: yesTongxin xuebao, 2006
Based on one kind of layered space-time code which used bit-interleavered and random-layered model,a joint detection-decoding method based on the Turbo principle was proposed.The new method used soft-interference canceller and SISO decoder and improved ...

Downlink Space–Time Spreading Using Interference Rejection Codes

open access: yes, 2006
In this paper, the authors will investigate the performance of a loosely synchronized (LS) code-based space–time spreading (STS) scheme in comparison to that of classic Walsh code and pseudonoise code-based STS when communicating over dispersive Nakagami-
