Apparatus and method for channel estimation

摘要

In a channel estimation method, an input signal is received. The input signal is then sliced to obtain a sliced signal. The multiplication of the input signal and the i^th delayed sliced signal are accumulated to obtain a cross-correlation value. The energy of the sliced signal is measured. The i^th channel parameter of a channel response is estimated according to the division of the cross-correlation value by the energy of the sliced signal. A channel estimator performing channel estimation is also provided.
