A space-time processing scheme is proposed for TDMA based cellular/PCS communications that cancels co-channel interference while simultaneously equalizing the desired signal. This is achieved through processing of a training signal designed from a PN code. At the receiver, the symbol waveform is built up above the noise and interference through correlation with a sampled waveform designed to ex...

|A procedure for obtaining a reduced complexity signal space detector is proposed and applied to the EEPR4 channel combined with d = 1 code. For the channel considered, the signal space detector requires at least 10 observation samples to attain the same minimum distance as the Viterbi algorithm (VA). The resulting signal space detector can be implemented with 7 linear discriminant functions, 1...

BACKGROUND The formulation and implementation of national ethical regulations to protect research participants is fundamental to ethical conduct of research. Ethics education and capacity are inadequate in developing African countries. This study was designed to develop a module for online training in research ethics based on the Nigerian National Code of Health Research Ethics and assess its e...

This study explores the differences in pollution control performances of industrial enterprises with various ownerships in China – State owned (SOE), collectively or community owned (COE), privately owned (POE), foreign directly invested (FDI) companies as well as joint ventures. A survey was conducted of approximately 1000 industrial firms in three provinces in China, which collects the detail...

Throughout history, societies have developed their own codes of ethics, including those pertaining to the practice of medicine. In the United States, physicians have adopted a set of ethics based on religious values and historical teachings. We, as physicians, have been presented several codes of ethics, including the American Medical Association Code of Ethics and the American College of Radio...
