Abstract

High Speed Single Frequency Network (HS-SFN) is one of the possible multi-cell transmission schemes for High-Speed Downlink Packet Access (HSDPA). This technique helps user equipments (UEs) in the softer handover area by combining signals from two neighbouring cells and also by reducing intercell interference. However, combining of two signals does not always have positive impact due to uncorrelated fast fading. This problem can be solved if the transmitted signals from the cells are adjusted such that the signals would arrive in phase. In this article the impact on HS-SFN is shown when phase adjustments are applied.
