Due to real-time nature of multimedia data, the 802.11ac standard applies the EDCA method to prioritize different types of traffics. The EDCA method supports four different access categories each with its own queue so that the highest priority is ass

In this paper, a method to suppress the impact of the nonlinear effects on an all optical orthogonal frequency division multiplexing (AO-OFDM) system is proposed. By inserting a guard interval (GI), the duty cycle of the optical signal in each symbol

In this paper, we address the Alamouti code in Filter-Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM), and propose a novel block-wise Alamouti code, in which a repeated block is designed to eliminate the imaginary interferen
