Understanding user-induced effects on signal reception across multiple frequency bands is of great scientific and military importance to the wireless industry. Various on-body locations and directional heading of the user are believed to impact the performance of mobile devices, but there has been little work across multiple frequency bands to quantify these user-induced effects. In this work, we...

Enabling device-to-device (D2D) communication in cellular network is shown to be a promising candidate in the future fifth generation (5G) wireless network. Specifically, the hybrid architecture leads to flexible and efficient resource allocation for cellular users and D2D users, thereby enhancing utilization of spectrum resources. However, if not properly handled, mutual interference will be significantly...
In an ad hoc network, efficiently scheduling the optimal multi-user multiple-input multiple-output links is challenging. Specifically, optimal scheduling requires full understanding of the subspace structure of the channel matrices, but exploiting this detailed information during scheduling requires significant computational and algorithmic complexity. This paper demonstrates efficient yet effective...
Because of the rapid variation in channel state information in multi-user networks with mobile nodes or scatterers, it is difficult both to maintain high communication performance using multi-user multiple-input multiple-output signaling and to create channel models that effectively represent the proper relationship between channels to different users as a function of their relative position. This...
For satisfying the requirements of broadband wireless access networks for high throughput and low delay, a delay sensitive scheduling algorithm based on simple network coding, DSNC, is presented. With the introduction of delivery state parameter, DSNC selectively combines retransmission packets into an innovative one by only XOR operation. Not only can DSNC reach the upper band of network throughput...
