Abstract
There are provided a spread code generating section generates a spread code list from the input parallel information, spread modulating sections generate a plurality of parallel spectrum spread signals corresponding to the parallel information list by multiplying each of the parallel information list and the spread code list respectively, phase shifting sections shift the phase of the parallel spectrum spread signals, delay sections delay the parallel spectrum spread signals. A multiplexing section generates a multiplexed spectrum spread signal by adding the delayed parallel spectrum spread signals. The multiplexed spectrum spread signal are converted into a radio frequency signal, amplified and then transmitted.
