A wireless terminal using switchable first and second reception antennas to perform diversity reception of data transmitted from a base station is proposed. The terminal includes an average value calculation unit that calculates an average value of a reception level measurement result of the first reception antenna and a reception level measurement result of the second reception antenna; and a correction unit that corrects the average value calculated on the basis of a predetermined thermal noise level, a received RSSI value measurement result of the first reception antenna, and a received RSSI value measurement result of the second reception antenna.

Wireless terminal and level measurement method

A digital adaptive equalizer equalizes received signals through digital filtering operations by changing filtering coefficients. It comprises a coefficient calculating unit for calculating the filtering coefficients by using one kind of parameters, such as distance, as an input to a function corresponding to the filtering coefficients and a filtering operation executing unit for executing digital filtering operations based on the filtering coefficients. A variable lag filter for adjusting the phase delay of received received signals is provided. A coefficient converting unit calculates a part or all of tap coefficients of the filter using at least one piece of timing control information.
