摘要：
A mobile communication system for modulating input data with a specific size into an OFDM (Orthogonal Frequency Division Multiplexing) symbol and transmitting the OFDM symbol through at least two different antennas. A replica generator generates replica data by cyclically-circulating the input data. An encoder generates a first antenna signal and a second antenna signal by encoding the input data and the replica data. A first IFFT (Inverse Fast Fourier Transform) block generates a first OFDM symbol by performing IFFT on the first antenna signal, and a second IFFT block generates a second OFDM symbol by performing IFFT on the second antenna signal. A first antenna transmits the first OFDM symbol, and a second antenna transmits the second OFDM symbol.
