Abstract: |
The present invention relates to a data adaptive mixed automatic retransmission method for orthogonal frequency division multiplexing system, belonging to the field of mobile communication technology. Said method includes the following steps: firstly, reading-in information bit, coding, modulation and storage; according to the output channel parameter making symbol reformulation for stored data, making OFDM demodulation, according to output channel parameter of system making adaptive deinterleaving for received data signal so as to obtain reduced data symbol, then making soft demodulation of data, combination of data and decoding to obtain information bit flow. |
