In this paper, we present a low-complexity algorithm for real-time joint transmit and receive antenna selection in MIMO systems. The computational complexity of exhaustive search in this problem grows exponentially with the number of transmit and receive antennas. We apply Binary Particle Swarm Optimization (BPSO) to the joint transmit and receive antenna selection problem. In addition, applying the...
In this paper, we consider the uplink communication in a network of cognitive radio nodes. The transmitting nodes and the receiver are equipped with multiple antennas and MIMO processing abilities. For this network, we study the problem of interference-aware joint secondary user (SU) selection/scheduling and power control (JSUS-QPC). The main objective of the JSUS-QPC is to maximize the sum-rate capacity...
In this paper, we investigate interference-aware joint secondary user (SU) selection/scheduling and quantized power control (JSUS-QPC) schemes for the uplink communication in the cognitive MIMO system. The main objective of the JSUS-QPC is to maximize the sum-rate capacity of the cognitive MIMO uplink communication system under the constraint that the interference to the primary users (PU) is below...
In this paper, we present a real-time low-complexity joint transmit and receive antenna selection (JTRAS) algorithm. The computational complexity of finding an optimal JTRAS by exhaustive search grows exponentially with the number of transmit and receive antennas. The proposed Estimation of Distribution Algorithm (EDA) is resorts to probabilistic distribution learning evolutionary computation. EDA...
In this paper, we present an iterative algorithm for detecting symbols at the receiver side in a multi-device (MD) STBC-MIMO System. We find that this algorithm has good performance especially at a low SNR region in rank-deficient MIMO systems. A multi-device system is a good example of a rank deficient system because the total number of transmit antennas are greater than the number of receive antennas...
In this paper, we present a real-time low-complexity joint transmit and receive antenna selection algorithm for MIMO systems. We apply ant colony optimization (ACO) to the joint antenna selection problem. The computational complexity of exhaustive search in this problem grows exponentially with the number of transmit and receive antennas. The proposed ACO for joint antenna selection has a low computational...
In this paper, we present a real-time low-complexity user scheduling scheme for uplink multiuser multiple input multiple output (MIMO) wireless communication systems. We apply estimation of distribution algorithm (EDA) for user scheduling problem. The computational complexity of exhaustive search for user scheduling problem grows exponentially with the number of users. The proposed EDA has low computational...
