In this paper, a novel two-stage coexistence detection scheme for 60-GHz millimeter-wave (mmW) WLAN/WPAN is proposed. Specifically, orthogonal frequency division multiplexing (OFDM) is employed as the transmission mode. The energy detector (ED) is used at the first stage to perform coarse scan. If required, the arithmetic mean to geometric mean detector (AGD) is invoked at the second stage to refine...
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...
In this paper, we propose a novel two-stage detection framework to facilitate the coexistence detection for OFDM-based 60-GHz millimeter-wave (MMW) WLAN/WPAN. Either blind or non-blind detection scheme can be employed at both stages regarding practical concerns. Here, the “non-blind” only refers to the case that relies on the prior knowledge of the noise variance. On the other hand, the blind detection...
In order to design a simple and highly accurate channel estimator for wireless personal area network systems, this paper proposes Golay sequence aided channel estimation. To evaluate the performance of proposed channel estimation, bit error rate performance of single-carrier transmission with frequency-domain equalization has been analyzed by computer simulation. When 8PSK modulation and Reed-Solomon...
The paper presents a feasible frequency domain pre-equalization (pre-FDE) proposal in order to reduce the number of frequency domain equalizer (FDE) in a piconet. The pre- equalization scheme based on the cross-layer design on both physical layer and MAC layer is proposed and investigated in millimeter-wave 60-GHz wireless personal area networks (WPANs). The physical structure is designed so that...
