Linear precoding for MIMO system based on imperfect CSIT

  title={Linear precoding for MIMO system based on imperfect CSIT},
  author={Li Chun-yan},
This paper bases on a dynamic CSIT model which utilizes the statistical information of the channel.Firstly,aiming to minimize the average codeword error probability,a performance criterion is derived.Then,by variable substitution and standard convex optimization algorithm,the best linear precoder is deduced.Upon these,the paper proposes a transmission scheme combining the orthogonal space-time block codes and the optimal linear precoder.Simulation results demonstrate significant gains and… CONTINUE READING
