In this paper, we propose a new miniaturized dual band frequency selective surface (FSS) for Wi-Fi applications. The proposed FSS possesses 0.42 GHz and 0.30 GHz bandwidths with insertion loss less than −15 dB around the two central operating frequencies 2.4 GHz and 4.6 GHz, respectively. The FSS exhibits excellent miniaturization with 0.057⋋1 × 0.057⋋1 or 0.11⋋2×0.11⋋2 unit cells, where ⋋1 and ⋋2...
In this letter, we propose an anchor-shaped loop unit-cell structure for compact frequency selective surfaces (FSSs) with dual-bandstop behavior in two wireless local area network (WLAN) frequencies 2.4 and 5.0 GHz. The proposed FSS possesses 230- and 300-MHz bandwidths with insertion loss less than 20 dB around the two central operating frequencies 2.4 and 5.0 GHz, respectively. In addition, the...
The paper proposes an analytical model, which deals with the throughput of 802.11 DCF in presence of hidden nodes under saturation condition. Different scenarios are used in simulation to validate it, and the results show that the model is fairly accurate.
In this paper, a real-time speech to speech translation (S2ST) system in mobile environment is designed and implemented as a client-server architecture. Particularly, we apply cross lingual speaker adaptation to adapt synthesized speech to enrolling speaker to ensure personalization. This realtime S2ST system provides streaming way, multi-threading and speaker adapted speech to speech translation...
