Abstract
An apparatus and method are provided for receiving data generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping in a wireless communication system. A fast Fourier transform (FFT) processor receives in-phase/quadrature phase (I/Q) data of a radio channel generated by sequentially performing bit interleaving, symbol interleaving and symbol mapping, and performs an FFT process for the I/Q data. A symbol deinterleaver performs a process for symbol deinterleaving the FFT I/Q data and reference values to be used for symbol demapping of the I/Q data and outputs the symbol-deinterleaved I/Q data and reference values. A symbol demapper performs a process for symbol demapping the symbol-deinterleaved I/Q data according to the reference values. A bit deinterleaver performs a process for bit deinterleaving the symbol-demapped data. A demultiplexer demultiplexes the bit-deinterleaved data.
