Abstract

A method and apparatus for transmitting and receiving a signal in a communication system are provided. The method includes setting a range of a Signal-to-Noise Ratio (SNR) having a varying threshold value according to a target Bit Error Rate (BER), receiving a signal from the transmitter through the wireless channel, measuring SNRs of all the antennas, selecting an antenna having the highest SNR among the measured antenna- specific SNRs, determining a range corresponding to the SNR of the selected antenna on the basis of the target BER and the set SNR range, and determining a modulation mode according to the range, and transmitting the determined modulation mode to the transmitter.
