چکیده

Cross-layer design approaches are critical to efficiently utilize radio resources. Resource allocation decision is made by assuming a single user. Multiple access scheme used is an Orthogonal Frequency Division Multiple Access (OFDM). With the goal of choosing best error detection technique, various techniques are compared. A resource allocation algorithm is required to efficiently allocate power and subcarriers. Water filling charts show the final results for initial power allocation and final

OFDM-MAC algorithms and their impact on TCP performance in next generation mobile networks

With the increasing adoption of wireless technology, it is reasonable to expect an increase in the demand for supporting both real-time multimedia and high rate reliable data services. Next generation wireless systems employ Orthogonal Frequency Division Multiplexing (OFDM) based physical layer owing to the high data rate transmissions that are possible without increase in bandwidth. Towards im...

A Fair Radio Resource Allocation Algorithm for Uplink of FBMC Based CR Systems

Spectrum scarcity seems to be the most challenging issue to be solved in new wireless telecommunication services. It is shown that spectrum unavailability is mainly due to spectrum inefficient utilization and inappropriate physical layer execution rather than spectrum shortage. Daily increasing demand for new wireless services with higher data rate and QoS level makes the upgrade of the physica...

Cross-layer Resource Allocation for Multi-user Communication Systems a Dissertation Submitted to the Department of Electrical Engineering and the Committee on Graduate Studies of Stanford University in Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy

Satisfaction of different QoS demands for various broadband services in wireless networks requires that multi-user packet scheduling intelligently use both channel state information (CSI) and queue state information (QSI). A combination of queuechannel-aware scheduling and power/rate allocation on each transmit dimension is known as “cross-layer resource allocation”. This thesis investigates va...

Cross-layer Packet-dependant OFDM Scheduling Based on Proportional Fairness

This paper assumes each user has more than one queue, derives a new packet-dependant proportional fairness power allocation pattern based on the sum of weight capacity and the packet’s priority in users’ queues, and proposes 4 new cross-layer packet-dependant OFDM scheduling schemes based on proportional fairness for heterogeneous classes of traffic. Scenario 1, scenario 2 and scenario 3 lead r...
