发明名称 Multi-channel communication
摘要 A multiple communicating apparatus has a multiple communicating unit for communicating data through a plurality of channels and a control circuit for controlling the multiple communicating unit in a manner such that the transmission electric power of each channel is inversely proportional to the number of channels which are used by the multiple communicating unit. The control circuit includes a channel control circuit for controlling the number of channels which are used by the multiple communicating unit in accordance with a transmission speed. The multiple communicating unit includes a diffusion circuit for diffusing parallel data by a plurality of diffusion code series. The multiple communicating unit transmits a multiple number for a preamble period of time provided for the reception side to synchronize the plurality of code series which are used for a code division multiple with the transmission side.
