摘要：

Single-carrier frequency domain equalization (SC-FDE) has been standardized as an alternative of orthogonal frequency division multiplexing (OFDM) in IEEE 802.11ad and 802.15.3c. In addition, with the use of low density parity-check (LDPC) codes, multi-Giga bits transmission can be supported in 60-GHz millimeter-wave (mmW) WLAN/WPAN with desired decoding complexity. In this paper, we present and evaluate an enhanced log-likelihood ratio (LLR) calculation method to facilitate the LDPC decoding in SC-FDE. In contrast to the virtual channel (VC) based LLR calculation approach (i.e., the Unique Word (UW) tracking scheme), our proposed method exhibits better bit error rate (BER) performance, and is more spectrally efficient.
