Abstract :
The paper validates the feasibility of auto-tuning of service- and bit rate-specific EbNo (Eb/N0) requirements. The EbNo requirement is the level of the received bit energy to the interference and noise density that the receiver equipment requires for proper decoding of the signal. The planned EbNo values can be used e.g., to scale the powers when the service is varying. The proposed methods, one for uplink and one for downlink, are tested using a dynamic WCDMA system simulator with a deployment of macrocells on a city region whose measured propagation characteristics have been incorporated into the model. The results show that the proposed methods tune the initially incorrect planned EbNo values so that the throughput in the system increases.
