Synchronization 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 کاملAdaptive Subcarrier Assignment and Power Distribution in Multiuser OFDM Systems with Proportional Data Rate Requirement
A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...
متن کاملA Low-complexity Power and Bit Allocation Algorithm for Multiuser MIMO-OFDM Systems
In this paper, we present a low-complexity bit and power allocation algorithm for multiuser MIMO-OFDM downlink transmission. In order to minimize the total transmit power under the condition that users'QoS requirements are satisfied, a novel resource allocation scheme is proposed to exploit the multiuser diversity gain. The proposed algorithm involves adaptive subcarrier allocation, adaptive mo...
متن کاملDynamic Resource allocation Algorithm for OFDM systems (LTE standard)
Dept. of computer Science and Mathematics My Ismail University Meknes FSM, Morocco This paper proposes a resource allocation algorithm for MIMO-OFDM systems (LTE standard). The algorithm is developed for orthogonal frequency division multiple access (OFDMA) system with frequency hopping and adaptive subcarrier-based assignment. The best subcarriers are assigned to each user by applying multiuse...
متن کاملDynamic Sub-Channel Allocation in Multiuser OFDM Systems to Achieve Variable Data Rate
This paper investigates the problem of dynamic multiuser subchannel allocation in the downlink OFDM systems. In traditional TDMA or FDMA systems, resource allocation for each user is non-adaptively fixed. Since the subchannel allocations among the users are not optimized, a group of users is likely to suffer from poor channel gains resulting from large path loss and random fading. To resolve th...
