Uplink Joint Resource Reallocation in a Multi-homing Heterogeneous System Based on Cognitive Radiohoming heterogeneous system with limited original subcarriers. Currently, all relevant works consider systems where networks run in separate frequency bands. Unlike them, we assume that they are capable of sharing spectrum resources by adopting CR to improve the resource utilization efficiency. Unli

Spectrum Access Strategy with Two-Way Cooperation Based on Joint Allocation of Time and Bandwidthallocation of time and bandwidth. In the strategy, the unit transmission time is divided into three time slots. Primary users (PU) communicate with each other in the first two time slots with the help of secondary user. Thus the secondary user can access the spectrum to transmit its own signal in th

Intermediate Performance of Rateless Codes over Dying Erasure Channelstly, we propose a heuristic approach for suboptimal degree distributions based on AND-OR tree technique to achieve higher intermediate performance. Secondly, the optimal code length for the maximum average date delivery ratio is derived and analyzed. Simulation results demonstrate that our coding s
