Iterative data detection and channel estimation for single-parity check-product coded MIMO wireless communications system

摘要

In iterative data-detection and channel-estimationudalgorithms, the channel estimator and the data detectorudrecursively exchange the information order to improve theudsystem performance. In this paper, maximum a posteriori based iterative data detection and pilot symbol assisted channel estimation of the single parity check product code for multiple antenna wireless communication is studied. Results show the algorithm can converge at a few iteration numbers and improve error probability performance of the system.
