Abstract | There is strong evidence that LDPC codes under practical all-integer quantization decoding constraint can achieve very good BER performance over binary modulation scheme, e.g., BPSK. By focusing on higher order modulation scheme, the effect of all-integer quantization decoding is further investigated in this work. Our result reveals that LDPC coded M-QAM with only 3-bit integer quantization decoding can exhibit excellent performance, i.e., negligible performance loss comparing with non-quantized case. |
