Abstract

A transmitter receiver implementing both frequency division duplex and time division duplex in one device in a CDMA mobile communication system. In the FDD mode, data in an interleave memory in an interleaver is read at a predetermined read rate VR = VN, where VN is a normal rate. In the TDD mode, a transmitting carrier frequency is set identical to a receiving carrier frequency, and the read rate VR of the interleave memory and the write rate VW of the deinterleave memory are set at VR = VW > 2VN.
The transfer rate VT from column to column of the memories are set identical in the FDD mode and the TDD mode. This makes it possible to create a vacant duration while transferring from column to column, and to perform reception or transmission during the vacant duration. The remaining operation of the TDD mode is the same as the operation of the FDD mode.
