Abstract
A to-be-sent signal ( ) is comprised of a header ( ) and convolution encoded data ( ). An error correcting code ( ) has a capability to correct a bit error or burst error contained in an objective data ( ) placed apart from the header ( ) in said convolution encoded data ( ). Because an error arises easily in data placed apart from a header compared with that positioned near said header generally, said error correcting code ( ) is added to data placed apart from said header and the addition of said error correcting code is omitted in data placed near to said header, thereby reducing whole information contents and transmission power.
