Wireless communications and digital transmission

点击翻译按钮获取中文摘要

Wireless communications research has been given great impetus by the advent of cellular telephony, mobile satellite and portable personal communication services. The exponentially growing user demand for services, together with the increasing demands for higher speed transmission of large amounts of data, as well as customer requests for multi-media services, create the need for new technologies. In order to provide higher data transmission rates to more users without sacrificing the integrity of the received information, advances must be made in the transmission system designs and in the transmission system components. In turn, achieving the best advances in wireless systems and components requires better estimation of the wireless channels in practical systems, and better modelling of the wireless channels in engineering design studies.
