This paper presents a path selection algorithm in conjunction with (2,2) Alamouti's space-time block code with pre-coding scheme (STBC-PC) to improve the network performance of a dual-hop amplify-and-forward cooperative mobile network. STBC-PC is applied to this study in order to employ STBC with single antenna which is incorporated in any wireless portable(More)
This paper proposes a concept for design and fabrication about a compact microstrip bandstop resonator for dual-band wireless communication. This proposed microstrip bandstop resonator is constructed from 2 open-circuited quarter wave-length transmission line stubs and J-inverter which are used to separate widely between low and high frequency bands by(More)
