When the electromagnetic waves propagate over the sea surface, there exists reflection, scattering and diffraction. Impact of sea clutter to the communication link is an important issue to evaluate and demonstrate. In this paper, we simulate the communication transmitter and receiver and use the theory of random bridge to build a random multipath channel model of the sea surface. Combined with typical...
In this paper, we investigate the impact of the asynchronism on the performance of a Cognitive Radio (CR) network, using the underlay paradigm. We are also compareing this effect depending on which modulation technique we are using. We provide a new the theoretical aspect of interference analysis in the context of orthogonal frequency division multiplexing (OFDM) and the Filter Bank Multicarrier (FBMC)...
In this paper, an order reduction maximum likelihood (OR-ML) algorithm for spatial modulation systems is proposed to reduce the receiver complexity. The proposed algorithm relies on a smaller order neighbourhood constellation which is relative to the conventional mapping constellation, where the active transmitting antenna indices or the possible quadrant transmission symbols locate in is obtained...
