Abstract

A coding unit and a radio transmitting unit are included. The coding unit includes a first coding unit, a division unit, and a second coding unit. The first coding unit codes information bits by using first coding. The division unit divides an output from the first coding unit into blocks. The second coding unit performs error correction coding on each of the blocks output by the division unit to generate a coded block. The radio transmitting unit transmits a plurality of the coded blocks at a random transmission timing.
