Abstract:
1. A code generation apparatus, comprising: a clock signal generator configured to generate a clock signal of a first frequency; a timing signal generator configured to generate, according to the clock signal, a timing signal of a second frequency lower than the first frequency; a storage in which a plurality of code sequences serving as a source for a pseudo-noise code is stored; a code sequence selector configured to select, according to the timing signal, a code sequence to be read, from among the plurality of code sequences stored in said storage; a partial code sequence extractor configured to extract, as a partial code sequence, a code of a predetermined bit length, from the code sequence selected by said code sequence selector; and a code outputter configured to output, by one bit at a time, according to the clock signal, the partial code sequence extracted by said partial code sequence extractor.
