PURPOSE: To eliminate the need for a multiplexer and a demultiplexer for reception by comparing each data word with its precedent data word and providing a 2nd control signal when both words match each other. CONSTITUTION: A service signal of a digital radio line which transmits an (m)=bit (m: natural number larger than 1) by modulating a carrier into n=2m states is transmitted is transmitted, bit by bit, by a method which adds the state of a carrier, transmitted to the position of the state corresponding to a following data word to (n) ((n+1)th state) when the data word is in the same state with the precedent state. Consequently, those signals having relatively high output can be transmitted without overdeforming a transmission spectrum or using excessive machine materials. |
