PROBLEM TO BE SOLVED: To provide a system which has comparatively high resistance to the fading, shadowing, etc., can improve its quality and also can shorten the guard time and increase the cell radius in a TDD(time division duplex) system by performing the chip interleaving processing to the spread transmitting data.SOLUTION: The transmitting data 101 are spread at a spreading part 102 and then undergo the chip interleaving processing at a chip interleaving part 107 at the transmitter side. The interleaved signals are modulated at a modulation part 103, amplified at a transmitting amplifying part 104 and radiated through a transmitting antenna 105. At the receiver side, the signals which are received through a receiving antenna 111 are detected at a detection part 112 and rearranged in a way opposite to the transmitting chip interleaving at a chip interleaving part 117. The deinterleaved data are synthesized at an inverse spreading part 113 and the receiving data 114 are obtained.
