Apparatus and method of data reception for wireless communications system using bit interleaving, symbol interleaving and symbom mapping

The present invention relates to apparatus and a method for receiving data generated through as bit interleaving, symbol interleaving, symbol mapping in a wireless communication system order. The bit interleaving in a wireless communications system according to the present invention, the symbol interleaving unit for receiving the generated data via a symbol mapping order is bit interleaving, symbol interleaving, generated through the symbol mapping order is received over a radio channel such phase (I) / quadrature (Q) and the I / Q data to the data as inputs the fast Fourier transform (FFT) FFT unit for the fast Fourier transformed I / Q data and the symbol di of the I / Q data according to the reference value to be used in the mapping, the symbol de-interleaver, and the reference value of the symbol de-interleaving and outputting the symbols deinterleaved I / Q data and reference values ​​corresponding to the symbol interleaved, the symbol de-interleaving I / Q data a, and a symbol demapping unit for demapping symbols corresponding to the symbol mapping, diyne bit corresponding to the bit interleaving the mapped data, the symbol D. And a living-bit deinterleaver for. DVB-T / H, BIT INTERLEAVING, SYMBOL INTERLEAVING, SYMBOL MAPPING, SYMBOL DEINTERLEAVING, SYMBOL DEMAPPING, BIT DEINTERLEAVING
