METHOD FOR PRECODING AND DECODING DISTRIBUTING MIMO CHANNELS IN RELAY-BASED DF COOPERATIVE WIRELESS NETWORKS

摘要

It is well known that relay-based DF cooperative wireless networks outperform AF cooperative networks. However, this performance enhancement is achievable through considerable signal processing (precoding/decoding) at relay nodes. To reduce the precoding/decoding complexity, a method for precoding and decoding a distributive MIMO channel in the relay-based DF cooperative wireless network using EVD based on properties of Jacket transformations is provided.
