A Novel Channel Sensing Method for IEEE802.11n MIMO System

摘要：

　　Coexistence and interoperability between 20MHz and 40MHz device and modes of operation are addressed in standard IEEE802.11n system.It is mandate to give the channel state in receiving processing,since for 40MHz device and modes for it should not only fulfill the single 20MHz signal but also 40MHz signal receiver requirement.Both energy detection and carrier sense are employed to detecting channel state.In the case of 20/40M mode,the power difference between the two sub-channels is also detected in order to indicate the channel state accurately.The simulation results demonstrate that the performance of the proposed methods is much better than the methods which just taking the first step above.
