Abstract
The packet reception section of the cellular phone receives a packet transmitted from the base station and the transmission error detection section detects a transmission error of the received packet. When the transmission error is detected, the retransmission request transmission section transmits a retransmission request to request the retransmission of the packet in which the transmission error is detected, to the base station, and the sample timing control section shifts the sample timing of the A/D converter by a half clock.
Claims7
A mobile communication terminal, comprising:
- receiving means for receiving an analog signal;
- transmission error detecting means for detecting a transmission error of the analog signal received by the receiving means;
- retransmission request transmitting means that, when the transmission error is detected by the transmission error detecting means, transmits a retransmission request to request retransmission of the analog signal in which the transmission error is detected;
- and
- sample timing controlling means for controlling the sample timing of an A/D converter for converting the analog signal into a digital signal,
- wherein the sample timing controlling means shifts the sample timing of the A/D converter by a half clock when the retransmission request has been transmitted by the retransmission request transmitting means.
