Abstract

A device and method for generating orthogonal codes differing in length according to symbol rates. An orthogonal code length corresponding to a variable symbol rate is calculated to determine an effective bit number. A chip count value is sequentially generated up to a maximum value, which can be counted by the effective bit number. An orthogonal code is generated by a logic operation of an orthogonal code index which is converted into the binary number of the effective bit number and the sequentially generated chip count values.
