A Rank Criterion for Qam Space-time Codes with Application to Turbo Coding
نویسندگان
چکیده
SufJicient conditions to ensure QAM space-time codes achieve full space diversity in quasi-static fading channel are presented. The conditions are on code words or generator matrices instead of on every code word pair. This simpl@es the check of full space diversity of a code. Based on these conditions, full space diversity parallel concatenated turbo codes are proposed to use in a multiple element antenna environment. Comparing with space-time trellis codes, the simulations show it has robust performance at both quasi-static fading channel and time varying fading channel.

OPSK Space-Time Turbo Codes
This paper proposes a class of full space diversity QPSK space-time codes based on parallel concatenated convolutional (turbo) codes. A rank criterion of full space diversity is used in the design. Compared with space-time trellis codes, the simulations show it has robust performance at both quasi-static fading channel and time varying fading channel.

Sufficient conditions to ensure QAM space-time codes achieve full space diversity in quasistatic fading channel are presented. T h e conditions are o n code words or generator matrices instead of on every code word pair. This greatly simplifies the construction of full space diversity codes.
متن کاملNew Construction Rules for Space-Time Trellis Codes by Set Partitioning : (Turbo) Super Orthogonal Space Time Trellis Codes
This paper introduces new variations about the codes recently introduced by Jafarkhani & al named Super Orthogonal Space Time Trellis Codes (SOSTTC). Using powerful set partitioning rules, these codes are able to combine the coding advantage of STTC’s together with the advantage diversity of STBC. This partitioning is based mainly on the determinant criterion introduced first by Tarokh. Jafarkh...

313 that the best 8-ary constellation is either the 8-PSK, or 8-cross, or (1; 7) depending on the desired spectral efficiency. As for the case of 16-ary constellations, the most attractive signal set is rectangular 16-QAM for all spectral efficiencies of practical interest. These results have been confirmed by computer simulations of BICM schemes combining turbo codes and several signal sets. T...
متن کاملImproved Space-time Turbo Codes with Full Spatial Diversity over Integer Ring
In this paper, we propose the space-time turbo codes designed over integer ring for BPSK and QPSK modulation. The proposed spacetime turbo codes addeve the full spatial diversity and can be decoded using the iterative binary soft-input sofl-output (SISO) algorithm. The BPSK/QPSK binary rank criterion is used to find the interleavers which guarantee the full spatial diversity. It is shown that t...
