Title: Multicarrier radio transmission system
Inventor: KANEKO KEIICHI
IPC: H04L7/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a multicarrier radio transmission system with which satisfactory characteristics can be provided, even when plural transmitters are operated simultaneously, while using the same frequency or respective nearby frequencies. SOLUTION: A receiver 2 transmits information for symbol synchronization and information for carrier synchronization to transmitters 1-1 and 1-2, while using the prescribed frequency more than one. The transmitters 1-1 and 1-2 convert the information which should be transmitted to a multicarrier signal and the receiver 2 receives the transmitted information for synchronization, generates a carrier synchronizing signal and a symbol synchronizing signal, converts the multicarrier signal into the prescribed frequency via D/A sampling, while the generated carrier synchronizing signal is used and radiates radio waves at symbol timing, while using the generated symbol synchronizing signal.
