This paper proposes a new double iterative procedure for sum-rate maximization in a Multiuser MIMO system (MU-MIMO). The proposed algorithm is based on joint precoder and decoder optimization involving two different decoding schemes. For that we considered a precoding algorithm namely the iterative SJNR (Signal to Jamming and Noise Ratio) precoder combined with two iterative receivers. The first receiver...
In this paper we present a new practical method for sum-rate maximization for a Multi-User MIMO system. Through this work, we first establish a general formula for the optimal receiver derived from the sum-rate expression called MSR (Maximum Sum Rate) receiver. The obtained MSR receiver is a linear function of the used linear transmitter. In a second step, we introduce this receiver in an iterative...
In this paper, we propose some ameliorations and a comparison of linear closed form precoding techniques for Multi-User MIMO (MU-MIMO) systems. In fact, the sum-rate, one of the most important parameters in the design of communication systems, is analysed through the study of two existing linear precoding schemes. These schemes are the PU-MMSE precoder named PU-MMSE and the Max SJNR scheme (Signal...
The two-step indoor location estimation method based on received signal strength in wireless sensor network is proposed. Measuring the received signal strength (RSS) of radio signals transmitted by multiple training points in wireless sensor network, least-squares approach has been applied to determine parameters of signal propagation model. Consider the estimated parameters of the signal propagation...
The full rate, full rank golden code showed to overcome all previous codes in (2 x 2) multiple input multiple output (MIMO) uncoded system when decoded with maximum- likelihood (ML) detectors. Therefore, its efficiency motivates us to study the code performance with suboptimal detectors, precisely two detectors based on decision feedback equalizer (DFE) detection. The first one is a DFE detector with...
