Abstract
Wireless communication equipment for a CDMA cellular wireless system operating FDD communication and TDD communication of a simplified circuit structure reduces interference with a communication channel. A wireless transmitter for an SS-DS CDMA cellular wireless system operating FDD communications and TDD communications includes an FDD pilot channel for outputting pilot channel signals in an FDD band, an FDD control channel for outputting control channel signals in the FDD band, FDD communications channels for outputting communications channel signals in the FDD band, a TDD pilot channel for outputting pilot channel signals in a TDD band, and a TDD communications channel for outputting communication channel signals in the TDD band. The wireless transmitter does not have a TDD control channel for outputting control channel signals in the TDD band. Control channel signals are transmitted only in the FDD band.
