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 this paper we propose a novel multicarrier (MC) architecture to address the energy saving problem in WLAN applications. We refer to this scheme as hybrid filtered multitone (H-FMT). Depending on the channel condition, H-FMT wisely switches between Filtered Multitone Modulation (FMT) with orthogonal pulses and adaptive orthogonal frequency division multiplexing (A-OFDM). We show that H-FMT provides...
In this paper, we propose a low-complexity carrier frequency offset (CFO) estimation algorithm for OFDM based wireless LAN, IEEE 802.11a. The complexity of the arctangent operation to calculate the argument of auto-correlation for CFO estimation is reduced by a novel range pointer method. The proposed algorithm estimates fine CFO value first and then based on the fine CFO value, simple criteria is...
This paper proposes a MIMO-OFDM scheme reducing the computational complexity and providing comparable performance to QRD-M detection scheme in IEEE 802.11n. The proposed scheme checks the channel condition per subcarrier and then selects either ordered DFE scheme or adaptive QRD-M detection scheme according to that information. The post-detection SNR which judges channel condition depends on Moore-Penrose...
