Margin Adaptive Resource Allocation for Multi–user OFDM Systems by Particle Swarm Optimization and Differential Evolution
Like many wireless systems, Orthogonal Frequency Division Multiplexing (OFDM) needs proper allocation of limited resources such as total transmit power and available frequency bandwidth among the users to meet their service requirements. In this paper, different versions of two evolutionary approaches, Differential Evolution (DE) and Particle Swarm Optimization (PSO) have been applied for adapt...
متن کاملAdaptive Downlink Resource Allocation Strategies for Real-Time Data Services in OFDM Cellular Systems
This paper presents a detailed performance analysis of adaptive downlink resource allocation based on users’ instantaneous channel responses using power minimization (PM) and bandwidth constrained power minimization (BCPM) strategies. This study shows that, in cellular systems, where interference is a dominant factor, the link outage performance of a resource allocation strategy varies signific...
متن کاملSynchronization and Resource Allocation in Downlink OFDM systems
The next generation (4G) wireless systems are expected to provide universal personal and multimedia communications with seamless connection and very high rate transmissions and without regard to the users' mobility and location. OFDM technique is recognized as one of the leading candidates to provide the wireless signalling for 4G systems. The major challenges in downlink multiuser OFDM based 4...
متن کاملLow Complexity Greedy Power Allocation Algorithm for Proportional Resource Allocation in Multi-User OFDM Systems
Multi-User Orthogonal Frequency Division Multiplexing (MU-OFDM) is an efficient technique for achieving high downlink capacity in high-speed communication systems. A key issue in MU-OFDM is the allocation of the OFDM subcarriers and power to users sharing the channel. In this paper a proportional rate-adaptive resource allocation algorithm for MU-OFDM is presented. Subcarrier and power allocati...
متن کاملMulti-User Adaptive Resource Allocation Scheme for WLAN OFDM-MIMO Transmission
. Orthogonal Frequency division multiplexing (OFDM) has recently been proposed for use in high data-rate wireless systems. OFDM has an important property of spectrum utilization technique that distributes each tone, which is orthogonal with every other tone. The system capacity can be significantly improved by multiple transmit and receive antennas that are used to form Multi-input multi-output...
