A wireless transmission apparatus in which degradation of error-rate characteristics can be avoided without decreasing a data rate in the mobile communication using a pre-coding together with a FDE. In this apparatus, a modulation unit (102) modulates a first data among transmission data with a first modulation method and generates a first symbol string, a modulation unit (103) modulates a second data among the transmission data with a second modulation method whose modulation multi-level number is larger than that of the first modulation method and generates a second symbol string, and a reproduction unit (104) reproduces the second symbol string and obtains a plurality of second symbol strings. An arrangement unit (105) arranges the plurality of the second symbol strings to both sides of the first symbol string and a pre-coding unit (106) performs a pre-coding to each symbol string after arrangement.
A radio transmitting apparatus comprising:
A radio receiving apparatus that uses frequency domain equalization, the radio receiving apparatus comprising:
A block forming method in a radio transmitting apparatus that performs precoding, the block forming method comprising:
