Systematic 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 کاملDesign of space-time trellis codes for full spatial diversity
Space-time codes have been developed to answer the need for high data rates in future wireless communication systems. In this work, we propose a systematic code construction method that provides full diversity advantage for any number of transmit antennas, any number of encoder states, and any constellation. Our approach is to exploit the properties of the state transitions in the trellis to fo...
متن کاملUniversal space-time trellis codes
This correspondence gives practical examples of space–time trellis codes performing as predicted by Root and Varaiya’s compound channel theorem. Specifically, 32-state and 64-state 2 2 space–time trellis codes are presented that provide a bit-error rate (BER) of10 on all2 2 matrix channels with an excess mutual information (MI) within 8% of the excess MI required by standard trellis codes of th...
متن کاملSpace-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 ...
متن کاملTurbo Equalization of Serially Concatenated Systematic Convolutional Codes and Systematic Space Time Trellis Codes
A novel turbo equalization arrangement is proposed, which is constituted by a serially concatenated systematic convolutional codec and a systematic space time trellis code (CC-SSTTC) assisted scheme. The BER performance of this scheme using various interleaving sizes was characterised over an equal-power twopath Rayleigh fading channel. After eight turbo equalization iterations, an interleaving...
