Human body communication (HBC) is an emerging communication technique for wireless body area networks, which has recently been included in IEEE802.15.6 standard. The HBC transmitter uses the frequency selective digital transmission (FSDT) scheme, where Walsh code are used to spread the information bits. The data rate of this system is limited to 1.3125 Mbps, due to the limited set of spreading codes...
In this paper, we investigate distributed control of multiple secondary users attempting to access the channel of a high priority primary user. Our aim is to maximize the sum cognitive (secondary) user throughput under the constraint of primary user's queue stability. We consider the effect of primary user link adaptation that allows the primary transmitter (PTx) to adapt its transmission rate in...
