PURPOSE:To improve working efficiency with conventional constitution by performing data spread by plural spread codes by allocating supplied data to be transmitted to plural channels. CONSTITUTION:The data sent out from a data supply means 450 is sent to a data control means 404 via an interface 402 according to the control of a control means 403. The control means 404 sends out the data to multipliers 406-408 on the plural channels simultaneously. On the other hand, a spread code generating means 405 sends out the spread codes set as to be sufficiently poor in mutual correlation to the multipliers 406-408. The data and the spread code arriving from the means 404 and 405 are multiplied by the multipliers 406-408, and any they are spread-encoded, mixed by a mixer 409 and transmitted. An inquiry signal supplied from a data supply means 401 for check is also sent to the control means 404. The control means 404 sends it out to all of registered channels placed on the control means 403, and transmits it in a simular manner. |
