Abstract
A multi-path receiving system is provided. The multi-path receiving system includes a multi-path analyzer, a channel estimator and an equalizer. The multi-path analyzer analyzes a channel impulse response (CIR) of the multi-path channel from the received stream. The channel estimator calculates a channel estimation result from the received stream. The channel estimator comprises a frequency domain interpolation filter performing channel estimation. The frequency domain interpolation filter consumes an amount of power according to the CIR result output from the multi-path analyzer. The equalizer equalizes the received stream based on the channel estimation result.
