This paper presents the design and the main performance results of a single-ASIC implementation of the recently proposed extended complex-valued blind anchored interferencemitigating detector (EC-BAID) for code division multiple access (CDMA) transmission. Such a detector, which exhibits a remarkable robustness to multiple access interference, operates in blind mode, i.e., it only requires know...
A set of physical layer specifications is provided for a single-band and a dual-band UWB system. Both systems fulfill the FCC regulations on UWB devices. Only the singleband system fulfills the physical layer requirements from IEEE 802.15.3a. The single-band system gives reliable communication, i.e., a 90th-percentile PER equal to 8% for 1024 payload bytes, at 110 Mbps with a transmitter–receiv...
Future wireless communication systems employ higher carrier frequencies and wider bandwidths than the 2G/3G systems. Moreover, dual-polarised antenna arrays will most probably be employed for improved coverage and higher data rates. As a result multi-dimensional knowledge of the mobile radio channel with fine resolution becomes available for adaptive utilisation of the channel capacity. At the ...
OBJECTIVE To evaluate the evidence for prenatal corticosteroid use in low- and middle-income countries and to make recommendations regarding implementation and further research. METHODS Studies and meta-analyses on prenatal corticosteroids relevant to low- and middle-income countries were identified and reviewed at the Maternal and Child Health Integrated Project (MCHIP) Antenatal Corticoster...
BACKGROUND Scaling up voluntary medical male circumcision (VMMC) to 80% of men aged 15-49 within five years could avert 3.4 million new HIV infections in Eastern and Southern Africa by 2025. Since 2009, Tanzania and Zimbabwe have rapidly expanded VMMC services through different delivery (fixed, outreach or mobile) and intensity (routine services, campaign) models. This review describes the moda...
background and purpose: birth outcomes and fertility measures are commonly evaluated in maternal and child health integrated program (mchip) in the field of public health. given the key role of time- trend study in the projection of current data to the future, this population-based study aimed to describe the significant changes of birth outcomes and fertility measures in the rural population o...
