Abstract :
A method that facilitates message exchange between spectrum heterogeneous secondary users in OFDM-based cognitive radio networks is presented. The proposed method utilises error correction coding to address spectrum heterogeneity. An example of how the proposed method is used to negotiate a control channel is provided.
