Patent ID: 7227908

Claim:
An information transmission apparatus for converting a format of input information into a predetermined format prior to transmission of said input information, said information transmission apparatus, comprising: first conversion means for converting a first information-bit sequence having a predetermined number of bits into a first encoded sequence having M numbers; first multiplication means for multiplying said first encoded sequence produced by said first conversion means by a first constant; second conversion means for converting a second information-bit sequence having a predetermined number of bits into a second encoded sequence having M numbers; second multiplication means for multiplying said second encoded sequence produced by said second conversion means by a second constant; wherein the first and second constants are based on a transmission energy for achieving a desired bit error rate; addition means for adding a constituent of a first constant-times encoded sequence produced by said first multiplication means to a constituent of a second constant-times encoded sequence produced by said second multiplication means to produce an additive encoded sequence; and transmission means for transmitting said additive encoded sequence as a transmitted signal.
