The optical wireless communication attracts much attention as an option for the indoor mobile communication technology. It utilizes the optical transmitter as a carrier source and photodiodes in the transmitted wavelength range as a signal detector. An indoor optical wireless communication system using convolutional coding is demonstrated by computer simulation. The data stream is coded into a convolutional...
Currently, many heat metering systems based on on-off valve regulation technology have the problems of unstable communication and high power consumption. To solve those problems, a new kind of heat metering systems based on on-off valve regulation technology has been advanced. It describes the components of the system. The principles and the scheme in the designing processes are presented in detail,...
