QPSK Balanced Space Time Trellis Codes
All the best known space-time trellis codes (STTCs) belong to the Balanced STTCs class. The first method to design balanced STTCs is proposed in this letter. The exhaustive code search of optimal codes can then be reduced to this class. Finally, the proposed method is used to construct new QPSK codes for 3 and 4 transmit antennas which outperform the best previously published codes of the same ...
متن کاملSystematic Design of Space-Time Trellis Codes for Diversity and Coding Advantages
The emerging need for high data rate wireless services has raised considerable interest in space-time coding. In this work, we propose a systematic code construction method that jointly considers diversity advantage and coding advantage for an arbitrary number of transmit antennas and any memoryless constellation. Our approach is to directly assign channel symbols to transmit antennas at differ...
متن کاملSpace-time trellis code construction for fast fading channels
The need for bandwidthand power-efficient wireless communication systems has raised considerable interest in spacetime codes. In this work, we propose a systematic space-time code construction procedure for fast fading channels. The method can be used to design space-time codes for an arbitrary number of transmit antennas and any memoryless modulation. We introduce a new design criterion that e...
متن کامل[hal-00617995, v1] QPSK super-orthogonal space-time trellis codes with 3 and 4 transmit antennas
In this paper, we propose, for the first time, QPSK super-orthogonal space-time trellis codes (SO-STTCs) with 3 and 4 transmit antennas and with more than 4 states. In order to decrease drastically the search time of the best SO-STTCs with 3 and 4 transmit antennas, a matrix representation of codes and an adaptation of the coset partitioning are proposed. Thus, we obtain good SO-STTCs with more...
متن کاملImproved high-rate space-time codes via orthogonality and set partitioning
In this paper, we propose a new technique for constructing improved high-rate space-time codes. The proposed code construction is based on a concatenation of an orthogonal spacetime block code and an outer M-TCM encoder. However, unlike the existing STB-MTCM schemes which are rate-lossy, the proposed construction yields higher-rate space-time codes by expanding the cardinality of the orthogonal...
