This paper compares the performance of a Turbo coded OFDM wireless link for SISO, SIMO, MISO and MIMO system with uncoded OFDM wireless link for SISO, SIMO, MISO and MIMO system in the in the presence of rayleigh fading. Turbo encoder encodes the input information bits and sends to QPSK or 16 QAM or 64 QAM modulator. Modulated symbols are mapped by STBC. Outputs of STBC are split into n streams...

Intruder detection method by utilizing a time variation of Multiple Input Multiple Output (MIMO) channel (MIMO Sensor) has been proposed. Although the channel capacity on the MIMO transmission is severely degraded in time variant channels, we can take advantage of this feature in MIMO Sensor applications. We have already demonstrated the effectiveness of 2×2 MIMO sensor using 2.4 GHz band at a ...

Blind source separation (BSS) technique using independent component analysis (ICA) for acoustic signals has been developed over the last decade. This technique assumes that the source signals are mutually independent, and can estimate the source signals from the mixed signals without a priori information. Thus, this technique is highly applicable in high-quality hands-free telecommunication sys...

In this paper, performance of a Turbo coded wireless link is evaluated in the presence of Rayleigh fading for single-input single-output (SISO), single-input multipleoutput(SIMO), multiple-input single-output (MISO) and multiple-input multiple-output (MIMO) system. Turbo encoded and 64-ary Quadrature Amplitude Modulation (QAM) modulated data are further encoded using spacetime block coding (STB...

Differentiated services (DiffServ) is the latest model proposed by Internet engineering task force (IETF) to support quality of service (QoS) in the Internet. It has flexibility and scalability advantages over the earlier model, namely, integrated services (IntServ). Currently, the DiffServ model is the preferred architecture widely accepted by Internet providers and the networking research com...

In the literature of blind equalization, algorithms developed for equalizing an SISO or SIMO channel fail sometimes when the channel condition is poor. We derive blind equalization algorithms from blind separation algorithms to equalize the SISO channel with fractionally sampling. The approach is also applied to equalize SIMO or MIMO channels. For switching channels, we use an updating rule to ...

BACKGROUND This systematic review evaluated the effectiveness of psychological interventions for reducing vaccination pain and related outcomes in children and adolescents. DESIGN/METHODS Database searches identified relevant randomized and quasi-randomized controlled trials. Data were extracted and pooled using established methods. Pain, fear, and distress were considered critically importan...
