This paper presents the strategy of combining antenna selection with an adaptive modulation scheme for Multiple Input Multiple Output (MIMO) systems. The proposed scheme maximized the Average Spectral Efficiency (ASE) with a constant power for a given Bit Error Rate (BER) constraint. This system provided the advantages of both antenna selection and adaptive modulation technique Also due to the practical...
The effect of DC offset on multi-input multi-output (MIMO) direct transceivers with adaptive modulation (AM) is discussed in this paper. A variable-rate variable-power (VRVP) AM system with perfect channel state information (P-CSI) at both the transmitter and receiver in a MIMO scenario is considered. The DC offset is modeled as a zero mean complex Gaussian distributed random variable. By this modeling...
This paper provides an intelligence method for medium and long-term energy demand forecasting of a complicated electrical system. In this method we use energy data of several past years to train an adaptive network based on fuzzy inference system (ANFIS). We use this intelligence network to estimate the time series behaviour of energy consumption for several future years. Several simulations have...
