    Abstract: Multi-code keying scheme is proposed for spectral-amplitude coding (SAC) optical code-division multiple-access (OCDMA) network, and in this scheme users are assigned several signature sequences for spectral efficiency enhancement. The shifted prime codes can be used in this scheme since their code patterns are suitable for the implementation of com... Show More

    Abstract: Power line carrier communication using 1MHz ~ 30MHz as carrier signal can improve the bandwidth of data transmission. Using the high frequency signal as a carrier signal, with the increase of signal frequency, the attenuation range of low voltage power line channel is also increased. On the basis of the structure of low voltage power grid, the tran... Show More
