1. Multirate Schemes and Multiuser Decoding in DS/CDMA Systems
Sammanfattning : Direct-Sequence Code Division Multiple-Access (DS/CDMA) has for some yearsbeen considered as a candidate for future personal and mobile communications.The reasons are mainly the properties of universal frequency reuse andthe multi-path mitigation. LÄS MER
2. Channel Coding and Multiuser Detection for CDMA and Wireless Communications
Sammanfattning : Next generation wireless communication systems will require support for many different applications as well as improved quality compared to existing second generation systems like GSM (Global System for Mobile communications). Since there will be more users and higher data rates, the capacity must also be increased. LÄS MER
3. Superconductor Digital Signal Processor
Sammanfattning : Superconductor digital technology based on Rapid Single Flux Quantum logic (RSFQ) offers more than 50 times gain in speed and more than 100 reduction in power consumption over mainstream CMOS devices. However, the necessity of cooling down to 4 K and modest degree of integration density currently available mean that employing RSFQ is reasonable only for the tasks that are impossible or ineffective to implement in CMOS technology.

4. Synchronization and data detection in long-code CDMA systems / Pei Xiao %C Göteborg
Sammanfattning : .... LÄS MER
5. Coding, Modulation and Multiuser Decoding for DS-CDMA Systems
Sammanfattning : The general trend both in wireless and fixed network communication systems is flexibility in services, data rates, desired delay and performance. Future systems should not be designed for specific services but be more general and allow for a multitude of services, both now existing and those not yet invented. LÄS MER
