Apparatus and method for measuring an SINR in a mobile communication system using preambles. Calculated are an average noise power using a CP of an RX signal, a signal power of a serving segment, an average power of the serving segment, and an interference power of the serving segment, an average power of each interference segment, and an interference power of each interference segment using the difference between the calculated average noise power and the calculated average power. An SINR of the RX signal is calculated by dividing the calculated signal power of the serving segment by the sum of the calculated average noise power and the total interference power of all the segments.
