Abstract
A transmission device is disclosed in which user data are cross converted, at their base band, by the orthogonal transformers 31.about.34. Signaling data are collected at every integer which does not exceed the ratio of the user data to the signaling data and time division-like multiplexed by the multiplexer 20. The multiplexed data are crossly converted, at its base band, by the orthogonal transformer 35. The base band data cross converted by the orthogonal transformers 31.about.35 are added by the adder 40 and carrier modulated so as to be radio transmitted from the antenna 60.
