This paper describes design methods of MIMO (multiple input multiple output) AF (amplify and forward) relay system for multiuser processing which is useful for multi-cellular networks. Each source is allocated one relay terminal, and relays cooperatively work to mitigate interferences one another based on ZF (zero forcing) or maximum SINR (signal to interference plus noise ratio) criteria. The necessary...
This paper describes a design method of two-hop single and multiple relay systems in which sources, relays, and destination are equipped with multiple antenna. The existence of interference signal and perfect CSI (channel state information) condition are assumed, and the design is carried out based on the maximum SINR (signal to interference plus noise ration) criterion. For multiple relay case, array...
This paper presents a subband adaptive array (SBAA) with reduced pilot signal based on maximal ratio combining (MRC) scheme. By the subband processing, MRC design based on eigenfiltering which is widely used in frequency flat environments could be applied to frequency selective channels, but the efficient synthesis of output signal through the inverse DFT (discrete Fourier transform) is disturbed...
This paper presents a maximal ratio combining (MRC) subband adaptive array using decision feedback approach. The subband adaptive array could extend the MRC scheme for frequency flat environments to be used in frequency selective channels, but the nonuniqueness of subband weights with respect to their phase rotation disturbs the efficient synthesis of output signal through the inverse DFT (discrete...
In this paper, we present a modified spatio- temporal adaptive array for multiuser space-time block codes (Modified STBC-TDLAA) transmission in frequency selective fading channel with the presence of co-channel interferences (CCIs). This method based on the transversal filter adaptive array perform the joint interference suppression and equalization. The presented Modified STBC-TDLAA can maximize...
