I/Q imbalance mitigation for STBC MIMO-OFDM communication systems

, 2008
In this work we study the performance degradation caused by the in-phase/quadrature (I/Q) imbalance in space-time block coded (STBC) multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication systems.

Blind recognition of STBC based on higher-order cumulants

Tongxin xuebao, 2016
Aiming at the problems for blind recognition of space-time block code(STBC)in MIMO communication sys-tems,a method was exploited based on higher-order cumulants of received signals.Firstly,the model of received signals was given and the fourth-order ...

Optimizing Quasi-Orthogonal STBC Through Group-Constrained Linear Transformation

, 2008
— In this paper, we first derive the generic algebraic structure of a Quasi-Orthogonal STBC (QO-STBC). Next we propose Group-Constrained Linear Transformation (GCLT) as a mean to optimize the diversity and coding gains of a QO-STBC.

Iterative interference cancellation based on decoding algorithm of space-time block coding in frequency-selective fading

Tongxin xuebao, 2006
Considering that the orthogonality of STBC in frequency-selective fading will be destroyed by the multiple path interference（MPI）,an iterative interference cancellation based maximum likelihood sequence estimation（MLSE） decoding scheme was proposed for ...
