Document Type and Number:
Japanese Patent JP2002044172
Kind Code:
A
Abstract:

To provide a phase correction circuit that uses an optimum channel estimate method to correct a phase of data and to provide a mobile radio terminal employing the circuit.

Channel estimate circuits 54, 55 of the mobile radio terminal for digital radio communication respectively generate a channel estimate value on the basis of a common pilot symbol and an interpolation pilot symbol. A selection circuit 56 selects a channel estimate value on the basis of either of the pilot symbols depending on a degree of a signal reception level or a fading from a base station and gives the selected value to the phase correction circuit 58 for data demodulation.
