Abstract:
1. A mobile communication terminal equipped with a multipath interference canceller for canceling multipath interference, comprising: an A/D converter configured to sample data from a received signal waveform; number-of-samples controlling means for controlling a number of samples to be sampled from the sampled received signal waveform received from the A/D converter; channel matrix generating means for generating a channel matrix on the basis of sample data of corresponding to the number of samples controlled by the number-of-samples controlling means; and interference canceling means for canceling multipath interference on the basis of the channel matrix generated by the channel matrix generating means, wherein the number-of-samples controlling means controls the number of samples to be sampled from the sampled received signal waveform received from the A/D converter in accordance with a number of taps of the multipath interference canceller by decreasing the number of samples when the number of taps is determined not to be less than a predetermined threshold, and setting the number of samples to be the same as a number of samples output from the A/D converter when the number of taps is determined to be less than the predetermined threshold.
