Abstract: PURPOSE: An automatic frequency control system of a receiver is provided to apply measured frequency offset to every proper data section after measuring a frequency offset between a base station and a receiver. CONSTITUTION: A data processing unit(100) calculates a signal to noise ratio from a channel impulse response of a received signal. The data processing unit compensates multi-path distortion of the received signal. A frequency control unit(200) calculates a frequency offset value of a currently received signal from a channel impulse response value calculated by the data processing unit and updated channel impulse response value. The frequency control unit calculates the average value of N frequency offsets determined as reliable frequency offsets based on a damage degree of a frequency offset value.

Abstract: PURPOSE: A method for improving channel quality of burst is provided to presume BEP through a BPMS value which is obtained from an optimum path and to reliably pedict a channel state. CONSTITUTION: A BPMS(Best Path Metric Sum) value is acquired from a BPM(Best Path Metric) value(30). A lookup table is composed according to a modulation mode(42). An acquired BPMS value is compared with a BPMS value on a lookup table(44). If the BPMS value on the lookup table exists, a BEP value corresponding to the BPMS value is converted in a linear scale(45,46).
