Dr. Min Song gave the keynote talk at IEEE GlobalSIP 2014 on December 5. The talk is titled “A Transparent Spectrum Co-Access Protocol for Primary and Secondary Users.” In this talk, Dr. Song introduced a novel wireless network protocol, termed spectrum co-access protocol (SCAP), for secondary users to transparently and simultaneously access the spectrum with primary users. SCAP enables mutually beneficial coexistence between primary user network and secondary user network. More details can be found at http://www.ieeeglobalsip.org/symposium/all-keynotes.html.
