A Review: Multi-Dimensional Space-Time Multilevel Codes using Rician Fading

This paper reviews multi-dimensional space-time multilevel codes (ST-MLCs). Basic construction methods, including conventional STCs. The spacetime multilevel encoders partition a dimensional signaling space, which spans all transmit antennas. Complexity of detection/ decoding can be reduced by multi-dimensional partitioning. Space time multistage decoder for the proposed ST-MLCs is reviewed. Th...

Multi-layered Space Frequency Time Codes

This dissertation focuses on three major advances on multiple-input multiple-output (MIMO) systems. The first studies and compares decoding algorithms for multi-layered space time coded (MLSTC) systems. These are single user systems that combine spatial multiplexing and transmit diversity. Each layer consists of a space time code. The detection algorithms are based on multi-user detection theor...

Space-time block codes versus space-time trellis codes

Transmit diversity schemes for the coherent multiple-antenna flat-fading channel range from spacetime block codes (STBC) to space-time trellis codes (STTC). In this letter we compare the performance of STBC and STTC by means of frame error rate. We discover that a simple concatenation of STBC with traditional AWGN (additive white Gaussian noise) trellis codes outperforms some of the best known ...

Advanced Receiver Algorithms for Multi- Layered Space-time Block Codes

In this paper we propose a new receiver architecture for multi-layered space-time block codes based on the QR decomposition and compare its performance to an alternative solution proposed by the authors based on MMSE. Both these algorithms use an iterative method based on soft decision statistics to cancel out interference from subsequent decoded layers and reduce the effect of error propagatio...

Space-Time Turbo Codes

Introduction: Recently, there has been a surge of interests in the design of the so called \space{time" codes which take advantage of both the spatial diversity provided by multiple antennas and the temporal diversity available with time{varying fading. The previous proposed space{time codes were mainly based on trellis codes or orthogonal block codes. In those codes, the number of transmitter ...
