Data transmitting-receiving system

DETAILED DESCRIPTION It is an object of the present invention to provide, in view of the above, a data transmitting-receiving system in which many coded points can easily be transmitted from technical and economic viewpoints and, thereby, to allow an increase in the data transmission capacity.
The above object is attained by the following.
In a transmitter, digital modulations are applied to the V-polarized wave carrier and the H-polarized wave carrier in which V- and H-polarized waves have the same frequency and are in synchronism with each other.
The digital modulations are achieved in accordance with data to be transmitted supplied via two separate routes.
Thus, a plurality of coded points corresponding to data are distributed in a three dimensional space and are transmitted to a receiver.
The receiver receives the coded points and reproduces the transmitted data therein.
According to the present invention, therefore, a unique digital modulation method is provided in which both the V-polarized wave signal and H-polarized wave signal are effectively utilized.
