1. On Performance Analysis of Retransmission Schemes with Fading Channels
Sammanfattning : Future wireless communication systems and services bring increased performance demands, with respect to data-rate(s), reliable communication, (stochastic) real-time guarantees, and more. In this context, not only new communication schemes are needed, but also more capable performance analysis methods are essential. LÄS MER
2. Hybrid ARQ Using Serially Concatenated Block Codes for Real-Time Communication : An Iterative Decoding Approach
Sammanfattning : The ongoing wireless communication evolution offers improvements for industrial applications where traditional wireline solutions causes prohibitive problems in terms of cost and feasibility. Many of these new wireless applications are packet oriented and time-critical. LÄS MER
3. Hybrid ARQ using serially concatenated block codes for real-time communication : an iterative decoding approach
Sammanfattning : .... LÄS MER
4. Improved Techniques for Retransmission and Relaying in Wireless Systems
Sammanfattning : The last three decades have seen significant advances in the wireless communication field. As the data rates of wireless systems are increasing, the demand for mobile services also is increasing rapidly. Like other natural resources, radio spectrum suitable for mobile wireless communications is also limited. LÄS MER
5. Convolutional Codes for Wireless Packet Data Systems
Sammanfattning : Automatic Repeat reQuest (ARQ) schemes can guarantee an almost error freereception strongly required in data communications. Hybrid type-II ARQschemes are supplied with channel coding to further improve the performance.In these schemes, error correction is performed adaptively which makesthem favorable for applications in time varying channels.
