Network coding has been proven as a very promising technique to improve wireless network throughput and energy-efficiency (EE). Meanwhile, cooperative caching, which allows the sharing and coordination of cached data among multiple nodes, can improve the performance of data access. In this paper, we aim at exploiting the potential benefits brought by cooperative caching for the multi-rate wireless...
Cooperative relay has been recognized as a promising approach for improving transmission efficiency and error performance in wireless networks. A number of realizations of cooperative relay communications, such as Amplify-and-Forward (AF), Decode-and-Forward (DF), have been proposed and the capacity gain of these replay approaches has been widely investigated. In this paper, we consider a cooperative...
Radio resource allocation strategy is one of the key issues in wireless CDMA cellular networks, which not only has to ensure that the system guarantees potentially different QoS requirements from diverse applications, but also fully utilizes the scarce wireless resources. Meanwhile, in CDMA cellular networks, successive interference cancellation (SIC) technique can be employed to reduce multiple access...
On the uplink of a DS-CDMA system, successive interference cancellation (SIC) technique can be employed to reduce multiple access interference and improve system capacity. In such a system with K active users, there are K possible decoding orders of SIC and not every decoding order is feasible due to some constraints. It is highly time-consuming to examine the system feasibility directly by using...
One of the key challenges in multi-services wireless cellular networks is the design of effective call admission control (CAC) algorithm, which not only has to ensure that the system guarantees potentially different QoS requirements from diverse applications, but also fully utilizes the scarce wireless bandwidth. On the uplink of a CDMA cellular network, successive interference cancellation (SIC)...
On the uplink of a DS-CDMA system with the imperfect successive interference cancellation (SIC) technique, K active users correspond to K! decoding orders. Due to the constraint of the received power, not all the possible decoding orders may be feasible, rendering the failure of SIC algorithm. Meanwhile, examining the feasibility of the system among all these decoding orders directly by the exhaustive...
One of the key challenges in multi-services wireless cellular networks is the design of effective access control policy (ACP) algorithm, which not only has to ensure that the system guarantees potentially different QoS requirements from diverse applications, but also fully utilizes the scarce wireless bandwidth. On the uplink of a CDMA cellular network, successive interference cancellation (SIC) technique...
