Long Term Evolution (LTE) has been proposed as a promising radio access technology to bring higher peak data rates and better spectral efficiency. However, scheduling and resource allocation in LTE still face huge design challenges due to their complexity. This paper divides the complex problem into three sub-problems: scheduling pattern, scheduling priority and quantity of scheduled data. Based on...
A critical challenge for mobile ad hoc networks is the design of efficient routing protocols that are able to provide high bandwidth utilization and desired fairness in mobile wireless environment without any fixed communication establishments. While extensive efforts have already been devoted to providing optimization based, distributed congestion elusion schemes for efficient bandwidth utilization...
The presence of the multi-access interference (MAI) limits the uplink performance of code division multiple access (CDMA). 2-dimensional (2D) block spread CDMA makes it possible to achieve MAI free uplink transmission while obtaining the frequency diversity gain by using low-complexity single-user frequency-domain equalization (FDE). To further improve the uplink transmission performance, the transmit...
