The multi-Gbps wireless personal area network (WPAN) operating at 60-GHz is being standardized in the task group of IEEE 802.15.3c. To deal with the multi-path delay spread in non-line-of-sight (NLOS) environments, single-carrier frequency-domain equalization (SC-FDE), a.k.a., single-carrier block transmission (SCBT), is used in the physical (PHY) layer design. The low-density parity-check (LDPC) coding is considered as the high-performance channel coding scheme due to its good tradeoff between performance and complexity. A series of structured LDPC designs  with very short codeword length of 576 are being adopted in one of the major proposals for IEEE 802.15.3c . The short codeword length helps to reduce the decoding complexity of LDPC. We evaluated the 576-length structured LDPC codes in SC-FDE system and found they have very good fixed point decoding performance. They are very promising in supporting ultra high-data-rate transmission with low complexity in 60-GHz WPAN (IEEE 802.15.3c).
