WCDMA Uplink Parallel Interference Cancellation—System Simulations and Prototype Field Trials

WCDMA Uplink Parallel Interference Cancellation - System Simulations and Prototype Field Trials

Interference cancellation (IC) is one identified key technology to enhance WCDMA uplink performance. The goal of this contribution is to highlight the relative uplink system capacity improvement available for WCDMA, especially in realistic typical urban radio environments when employing receiver implementations including realistic channel estimation, searcher, and so forth. The performance of t...

WCDMA Uplink Interference Assessment from Multiple High Altitude Platform Configurations

We investigate the possibility of multiple high altitude platform (HAP) coverage of a common cell area using a wideband code division multiple access (WCDMA) system. In particular, we study the uplink system performance of the system. The results show that depending on the traffic demand and the type of service used, there is a possibility of deploying 3–6 HAPs covering the same cell area. The ...

Uplink load estimation in WCDMA

All cellular radio systems depend on well performing radio resource management algorithms to efficiently utilize available resources. These algorithms make their decisions based on some sort of resource quantity. In the uplink of a WCDMA system, the total received power at the base stations is a natural choice of such a quantity. Unfortunately this quantity cannot be measured with enough accura...

Uplink Packet Scheduling in WCDMA Systems

The objective of this thesis report is to make a comparative study of three scheduling algorithms for the uplink of a WCDMA system restrictive, pre-emptive and random scheduling. Performance and complexity issues are addressed. To this end, scheduling algorithms were modeled in a MATLAB environment with predefined WWW traffic model. Interesting load scenarios were defined and simulated. Results...
