Bursty communication has gained recent interest with the advent of 5G and its focus on Machine to Machine (M2M) communication for applications such as Internet of Things (IoT). Such systems are often required to transmit sporadic data within a large window of transmission, while the receivers need to synchronize reliably. Synchronization costs are relatively large with sporadic data transfer setups as compared to their continuous counterparts. Asynchronous communication deals with characterizing the fundamental limits of communication when the transmitter and the receiver are not in synchrony.
In this talk, we present the optimum scaling factor between the sync word length and the transmission window size for error free packet synchronization over a finite state Markov channel (FSMC) for low rate devices in an asynchronous communication setup. We assume channel state information (CSI) is available to both the transmitter and the receiver. We, then, present a trade-off between transmission energy and detection delay using a Markov decision process (MDP) framework. Finally, we present achievable schemes for packet detection in scenarios where CSI is available only at the (a) receiver, and (b) transmitter.
All are cordially invited.
