A Kalman-Filter Method for Power Control in WCDMA
Cheng Shi · 2002
A Kalman filter method for power control is recommened for broadband packet switched CDMA wireless networks. Temporal correlation of interference can be observed when data are being sent continuously by transmitters. A Kalman filter can then be used to predict interference power. Based on the predicted interference and estimated path gain between the transmitter and receiver, transmission power is determined to achieve the desired signal to interference plus noise ratio(SINR). Simulation results reveal that the Kalman filter method for power control provides a performance improvement.
