Abstract :
With the development of single carrier-frequency domain equalization (SC-FDE), the scheme that channel state information (CSI) utilization at the transmitter has been proposed. In time-varying channels the CSI acquiring is a hard work which is important to CSI utilization techniques such as adaptive modulation and adaptive power control. In this paper we propose an improved adaptive RLS predictor in fast time-varying channels for SC-FDE system. The proposed predictor has a better performance than the existing. And the complexity of the proposed predictor is reduced
