Recent breakthroughs in wireless communication show that by using new signal processing techniques, a wireless node is capable of transmitting and receiving simultaneously on the same frequency band by activating both of its RF chains, thus achieving full-duplex communication and potentially doubling the link throughput. However, with two sets of RF chains,(More)
Imbalanced data sets have significantly unequal distributions between classes. This between-class imbalance causes conventional classification methods to favor majority classes, resulting in very low or even no detection of minority classes. A Min-Max modular support vector machine (M 3-SVM) approaches this problem by decomposing the training input sets of(More)
In this paper, we characterize the throughput of a broadcast network with n receivers using rateless codes with block size K. We assume that the underlying channel is a Markov modulated erasure channel that is i.i.d. across users, but can be correlated in time. We characterize the system throughput asymptotically in n. Specifically, we explicitly show how(More)
—Recent work has shown that retransmission-s can cause heavy-tailed transmission delays even when packet sizes are light-tailed. Moreover, the impact of heavy tailed delays persist even when packets are of finite size. The key question we study in this paper is how the use of coding techniques to transmit information could mitigate delays. To investigate(More)
OFDMA has been selected as the multiple access scheme for emerging broadband wireless communication systems. However, designing efficient resource allocation algorithms for OFDMA systems is a challenging task, especially in the uplink, due to the combinatorial nature of subcarrier assignment and the distributed power budget for different users. Inspired by(More)
The recent breakthrough in wireless full-duplex communication makes possible a brand new way of multi-hop wireless communication, namely full-duplex cut-through transmission, where for a traffic flow that traverses through multiple links, every node along the route can receive a new packet and simultaneously forward the previously received packet. This(More)
A novel mobile peer-to-peer (MP2P) in cellular networks is presented in this paper. The proposed architecture is based on Session Initiation Protocol (SIP) that is part of the IP Mul-timedia Subsystem (IMS) in the third-generation mobile cellular networks. In this architecture, P2P control messages are transported in SIP messages, so called P2PoverSIP. By(More)
For a multicast group of <i>n</i> receivers, existing techniques either achieve high throughput at the cost of prohibitively large (e.g., <i>O</i>(<i>n</i>)) feedback overhead, or achieve low feedback overhead but without either optimal or near-optimal throughput guarantees. Simultaneously achieving good throughput guarantees and low feedback overhead has(More)
—A major challenge of wireless multicast is to be able to support a large number of users while simultaneously maintaining low delay and low feedback overhead. In this paper, we develop a joint coding and feedback scheme named Moving Window Network Coding with Anonymous Feedback (MWNC-AF) that simultaneously achieves constant decoding delay and constant(More)
