PURPOSE: To provide a transmitting device of a compact circuit constitution which can reduce both arithmetic value and burden. CONSTITUTION: A data composition/generation part 101 compounds the transmission input data series of plural variable transmission rates and generates a single data series. In other words, plural pieces of different data of variable rates are recombined into N sets of data series with (i) of transmission data of a single frame divided into N pieces varying to I from 1. Thus a single composite data series Ak (t) is generated. A transmitting station identification code multiplication product part 102 multiplies the composite transmission data Ak (t) by bk (t) which is outputted from a code generation part 103 and gives a transmitted multiplication product code ck (t) to a transmission velocity conversion part 104. The part 104 receives the output from the part 102 and converts the data Ak (t) into the data dk (τ) of a prescribed transmission velocity to give it to a diffusion modulation part 105 regardless of the transmission velocity of the part 102. |
