Approximate minimum symbol error probability transceiver design of single user MIMO systems under the practical per-antenna power constraint is considered. The upper bound of a lower bound on the minimum distance between the symbol hypotheses is esta

This paper proposes a novel framework for analyzing the localization accuracy of data fusion for fingerprinting approaches in non-line-of-sight (NLOS) environments. Using simulation data generated for two very different NLOS environments (a suburban

With a tremendous amount of underutilized bandwidth, millimeter wave (mmWave) communication is a promising solution to meet the increasing data-rate demands. To deal with high pathloss in mmWave frequency band, efficient large antenna arrays become c

We consider a downlink Heterogeneous Massive Multiple-Input Multiple-Output (HM-MIMO) system with the macro-base station (BS) having hundreds of antennas and each of the micro-BSs having tens of antennas. Two lower bounds and one approximation of the

In a distributed massive multiple-input and multiple-output (DM-MIMO) orthogonal frequency division multiplexing (OFDM) system, each of the multiple receivers receives the OFDM signals simultaneously from all transmitters intended for itself and othe

Overlapping basic service set (OBSS) interferences cause significant reductions in the network throughput as seen at the medium access control (MAC) layer. When the frequency bands of multiple OBSSs are partially overlapped, the reduction of throughp

This paper proposes a cross-layer design for the stations (STAs) in a distributed coordination function (DCF) network. By selecting the modulation scheme, coding scheme, and packet length of each STA in the network, the design aims to maximize the to

This study presents an unsaturated two-dimensional (2D) Markov model to analyse the packet collision probability and the throughput performances of the stations (STAs) in a distributed coordination function network. Compared with the previous 2D mode

Presented in this study is a novel precoding scheme for orthogonal frequency division multiplexing systems to suppress the out-of-band emission (OOBE). The scheme suppresses the OOBE by making the transmitted signal satisfy the continuous derivative
