We consider the performance analysis of beam space-time of a multiple-input multiple output (MIMO) orthogonal frequency-division multiplexing (OFDM) systems for high data rate wireless transmission. The tools of density evolution with mixture Gaussian approximations are used to compute minimum operational signal-to-noise ratios (SNRs) for ergodic MIMO OFDM(More)
OBJECTIVE To study the efficacy of the protocol of combination of lamivudine with low dosage hepatitis B immuno-globulin (HBIG) to prevent HBV reinfection and of the treatment for HBV reinfection after liver transplantation. METHODS From December 2000 to May 2003, 11 patients (follow-up is more than 1 year) had been transplanted due to HBV related(More)
In this paper, we use ICALAB tool with our algorithm to extract the desired image of license plate captured by sensors, which will be essential used by vehicle positioning system (VPS). The use of the blind least mean square algorithm (BLMS) can often provide a useful method to extract the sources and independent component. The BLMS learning rule has a(More)
In the design of cascode CMOS low-noise amplifiers, the gate-drain capacitance is generally neglected because it is thought to be small enough compared to gate-source capacitance. However, a careful examination will reveal the fact that the drain impedance of the input transistor significantly affects the input impedance through the gate-drain capacitance,(More)
The frequency domain channel model for Rician fading channels has been applied. It allows performance results to be shown as a function of the channel parameters }, , , { 0 rms K P τ the normalized receiver power (NRP), the Rician K-factor, and root mean square (rms) delay spread (RDS). Assuming perfect channel estimation or, if differential schemes are(More)
Two-phase micro-pipeline asynchronous modules show faster performance than common four-phase control systems, but the conventional systems with multi-port modules normally suffer from long signal paths on stacked C-elements. NOR-based control schemes provide an alternative solution to problems such as propagation delay. This paper compares modified versions(More)
