1. An apparatus for measuring a bit error rate (BER) in an orthogonal frequency division multiplexing (OFDM) communication system, comprising:

  • a transmitter including;

    a pilot pattern inserter for inserting a first reference pilot pattern in subchannels of input data, and outputting reference pilot pattern-inserted transmission data; and

    an OFDM modulator for OFDM-modulating the reference pilot pattern-inserted transmission data; and

    a receiver including;

    a pilot pattern detector for OFDM-demodulating a data symbol received in a frame unit and detecting only a pilot pattern; and

    a BER operator for comparing the demodulated pilot pattern with a second reference pilot pattern, detecting and accumulating the number of pilot errors, and measuring a bit error rate by dividing the accumulated number of the pilot errors by the number of total received pilot patterns.
