A Space-Time Pre-RAKE Transmitter Diversity Method for W-CDMA Using Long Range Prediction
1 This research is funded by NSF grants CCR-9725271 and CCR-0081706 Abstract– Transmitter diversity in the downlink for Code Division Multiple Access (CDMA) systems provides a means to achieve similar performance gains as for the mobile-station receiver diversity without the complexity of a mobile-station receiver antenna array. Pre-RAKE precoding at the transmitter can be employed to achieve t...
متن کاملSpace-Time Diversity Techniques for WCDMA High Altitude Platform Systems
Third generation mobile systems are gradually being deployed in many developed countries in hotspot areas. However, owing to the amount of new infrastructures required, it will still be some time before 3G is ubiquitous, especially in developing countries. One possible cost effective solution for deployments in these areas is to use High Altitude Platforms (HAPs) (Collela et al., 2000; Djuknic ...
متن کاملCombined adaptive modulation and transmitter diversity using long range prediction for flat fading mobile radio channels
Development of novel signal processing and communication techniques for 3G wireless systems is motivated by high data rate service requirements. These techniques include adaptive modulation and transmitter antenna diversity. In rapidly time variant channels, these methods need the knowledge of future fading conditions. Thus, they require accurate long range fading prediction. We investigate thr...

در این پایان نامه نشان داده ایم که چگونه می توان مدل ریسک بیمه ای اسپیرر اندرسون را به کمک زنجیره های مارکوف تعریف کرد. سپس به کمک روش های آنالیز ماتریسی احتمال برشکستگی ، میزان مازاد در هنگام برشکستگی و میزان کسری بودجه در زمان وقوع برشکستگی را محاسبه کرده ایم. هدف ما در این پایان نامه بسیار محاسباتی و کاربردی تر از روش های است که در گذشته برای محاسبه این احتمال ارائه شده است. در ابتدا ما نشا...
15 صفحه اولPerformance Analysis of Long Range Prediction for Fast Fading Channels
Long range prediction capability for fading channels would provide enabling technology for accurate power control, reliable transmitter and/or receiver diversity, more effective adaptive modulation and coding and improvements in many other components of wireless systems. In order to achieve accurate long range prediction, the authors recently introduced a novel algorithm that finds the linear...
