RECEIVING DATA COMPENSATION METHOD TO IMPROVE DATA RECEIVING RATE AND RECEIVING MODEM CIRCUIT THEREOF
First Claim
1. A receiving data compensating method comprising:
- measuring a receiving characteristic offset based on characteristics of a receiver according to first and second state data;
independently deciding a first data sample time offset to correspond to the first state data and a second data sample time offset to correspond to the second state data; and
compensating receiving data by applying the first data sample time offset when the receiving data is the first state data and compensating receiving data by applying the second data sample time offset when the receiving data is the second state data.

Abstract
Included in the present general inventive concept are a receiving data compensating method to improve a data receiving rate and a receiving modem circuit thereof. The receiving data compensating method may include measuring a receiving characteristic offset based on characteristics of a receiver according to first and second state data. After measuring the receiving characteristic offset, a first data sample time offset to correspond to the first state data and a second data sample time offset to correspond to the second state data are independently decided. The decided first and second data sample time offsets are applied during compensation of receiving data received through a receiver. A near field communication (NFC) multimedia device may implement the receiving data compensation method.
