In this paper, performance of double binary turbo coded orthogonal frequency division multiplexing (OFDM) system is analyzed and simulated in power line communications (PLC) channel. In order to make power line channel environments, Bernoulli-Gaussian noise is considered. The performance is evaluated in terms of bit error probability. From the simulation results, it is demonstrated that the double...

Today, the improved wireless communication technique for increasing demand for the next generation communication system is developed variously to transmit a long distance and high data. Visible light communication (VLC) system uses radiated light of LEDs. However, VLC have weak points which deteriorate performance of communication. Because there is multi-path fading that occurs propagation delay by...
A recent trend of research on the MIMO-OFDM system pays more attention to reduce complexity for implementation in design receiver structure. So in this paper, we propose differential space time block codes (STBC) MIMO-OFDM system with cyclic delay diversity (CDD) in a frequency selective fading channel. Differential modulation provides simplification of embodiment communication system because channel...
