ICA based blind detection scheme in space-time block coding communications
Space-time block coding（STBC） schemes are capable of improving system performance by using transmit diversity strategy and specific coding schemes.Nevertheless,they need precise channel state information（CSI） at the receiver end in order to achieve good detection performance,which is difficult to be...

| description | Space-time block coding（STBC） schemes are capable of improving system performance by using transmit diversity strategy and specific coding schemes.Nevertheless,they need precise channel state information（CSI） at the receiver end in order to achieve good detection performance,which is difficult to be guaranteed in some specific scenarios because of complicated communication conditions.Independent component analysis（ICA） technique is to separate a complex data set into a couple of independent sub-sets,which belongs to the family of blind source separation（BSS） technique.ICA techniques were exploited into the STBC communication systems,and they were used to detect the transmitted signals blindly,which need not the channel estimation.After analyzing the essential structure of STBC system,the specific model suitable to ICA is established,and several typical ICA algorithms are adopted to make a comparison.The robustness against channel estimation errors can be acquired by using the ICA based schemes.Simulation results demonstrate the validity of proposed approaches,and after the comparison among different ICA based detection schemes,the optimal one is found and the discussions are also given. |
