“…It is worth mentioning that the PA strategy given in Equation 12 is found to correspond to the traditional waterfilling PA techniques which can provide high spectral efficiency [3]. Since the PA strategy is independent of the BA strategy, the transmit power can be waterfilled onto different subcarriers before implementing BA.…”

“…Among the emerging broadband wireless access technologies, orthogonal frequency-division multiple access (OFDMA) is a promising technique for efficient utilization of the available spectrum. Owing to its several attractive features, OFDMA has been envisaged for possible implementation in future-generation wireless networks, e.g., 3GPP-long term evolution [1], cognitive radio networks [2], and IEEE 802.20 mobile broadband wireless access [3].…”

This article presents a subcarrier allocation scheme based on a Blotto game (SABG) for orthogonal frequencydivision multiple access (OFDMA) networks where correlation between adjacent subcarriers is considered. In the proposed game, users simultaneously compete for subcarriers using a limited budget. In order to win as many good subcarriers as possible in this game, users are required to wisely allocate their budget. Efficient power and budget allocation strategies are derived for users for obtaining optimal throughput. By manipulating the total budget available for each user, competitive fairness can be enforced for the SABG. In addition, the conditions to ensure the existence and uniqueness of Nash equilibrium (NE) for the SABG are also established. An lowcomplexity algorithm that ensures convergence to NE is proposed. Simulation results show that the proposed lowcomplexity SABG can allocate resources fairly and efficiently for both uncorrelated and correlated fading channels.

“…As a result of the combined benefits of MIMO with OFDMA, this technology has been selected as the PHY Layer air-interface for WiMAX (802.16) whilst Third Generation Partnership Project (3GPP) has assumed OFDMA will be used as the downlink interface for the Long Term Evolution (LTE) network -an enhancement to existing 3G standards. The IEEE 802.20 Working Group has also nominated OFDMA as its packet-based air interface for future Mobile Broadband Wireless Access (MBWA) [2].…”

Abstract-For a single user with multiple receive antennas, coantenna interference can be the dominant source of impairment in a Spatial Multiplex Orthogonal Frequency Division Multiple Access (SM-OFDMA) system, particularly when correlation exists between spatial sub-channels. By exploiting knowledge of the channel response and combining it with Dynamic SubCarrier Allocation (DSA), the algorithm proposed in this paper aims to reduce the effect of interference, while providing fair gain and maximizing the SINR across all users. Simulation results reveal that the proposed algorithm considers self-interference that exists between multiple antennas and is capable of achieving a capacity gain for every user with improved BER performance compared to previous work.
