Rapid prototyping of multi-mode QC-LDPC decoder for 802.11n/ac standard
Qing Hua Lu, Chiu‐Wing Sham, Francis C. M. Lau · 2016
A multi-mode QC-LDPC decoder is proposed to satisfy the 802.11n/ac WiFi standard. With code-specific design, the overall performance of the decoder is enhanced while ensuring an on-the-fly reconfigurable ability. The proposed architecture has been synthesized using an FPGA for measurements. A state-of-art error rate and implementation complexity are reported. Meanwhile, the throughput has been increased to range from 382 MHz to 1852 MHz.
