Distributed Linear Dispersion Codes in Cooperative Communication
|
Abstract:
Distributed linear dispersion codes are proposed for the space time coding in wireless network where cooperative nodes can not be decided priori.The nodes in cooperation are coded with different dispersion vectors. The mutual information loss when the number of cooperative nodes decreased is conducted and a coding criterion of distributed dispersion codes is developed accordingly.The simulation results show that the distributed dispersion codes with the coding criterion achieve good performance.
