International ClassH04L 1/18AbstractA receiving apparatus in a communication system in which when a systematically encoded signal cannot be decoded correctly on a receiving side, the signal is retransmitted from a transmitting side. The receiving apparatus combines stored data, which has been generated based upon data already received, and newly received data, decides a range of quantization levels of the combined data using an average level only of systematic bits of the stored data and newly received data, quantizes the combined data based upon the range of quantization levels and number of quantization bits, applies decoding processing to the quantized data, notifies the transmitting side of whether decoding could be performed correctly, and stores the combined data as the stored data when decoding cannot be performed correctly.Other References
