资源说明：Abstract: The implementation of low-density parity-check (LDPC) codes will be a mandatory feature in the 2019 IEEE 802.11ax amendment, the sixth generation of wireless local area networks (WLANs) for frequencies below 6 GHz. Orthogonal frequency division multiplexing multi-user multiple-input multiple-output (OFDM MU-MIMO) technologies for both downlink and uplink have been specified in Task Group (TG) 802.11ax meetings to improve the spectrum and area efficiency in ultra-dense WLANs. In this paper, we compare the performance of binary convolutional codes (BCC) and LDPC codes using different configurations of multi-antenna technologies taking into account both hardware and system impairments. We have concluded that on the most study cases, the implementation of LDPC codes in the IEEE 802.11ax physical layer allows power gains between 2.5 and 4.0 dB in relation to BCC with soft-decision Viterbi decoding.
