Method for generating and allocating code pairs of orthogonal spreading codes

A method for generating an orthogonal code set using orthogonal spreading codes, said method comprising the following steps of:

• generating orthogonal spreading codes corresponding to a selected code length;
• adjusting the interval of the length of an IFW based upon a selected code component length;
• and
• generating at least one orthogonal code set based upon the orthogonal spreading code if the length of the IFW interval is adjusted.

A method for allocating code pairs using orthogonal spreading codes, said method comprising the following steps of:

• determining one of at least one orthogonal code set as a representative orthogonal code set;
• allocating different orthogonal spreading codes to an I branch and a Q branch, and judging whether to minimize a peak-to-average power ratio;
• generating at least one code pair based upon the representative orthogonal code set according to a result of said judging S 62 in FIG. 5;
• generating a code pair set based upon the at least one code pair;
• and
• allocating the code order based upon the at least one code pair included in the code pair set.

• allocating different orthogonal spreading codes to an I branch and a Q branch, and judging whether to minimize a peak-to-average power ratio;
• grouping at least one code pair set according to a rule determined based upon the representative orthogonal code set as a result of said judging S 62 in FIG. 5;
• selecting one from the at least one code pair according to a determined order;
• generating at least one code pair based on at least one element included in the selected code pair set;
• and
• allocating the code order based upon the at least code pair.

A method for allocating code pairs using orthogonal spreading codes, said method comprising the following steps of:

• determining one of at least one orthogonal code set as a representative orthogonal code set;
• judging whether to identically allocate the same orthogonal spreading code to an I branch and a Q branch;
• generating at least one code set by using the orthogonal code set according to a result of said judging S 61 in FIG. 5;
• selecting the at least one code set in a predetermined order;
• and
• allocating the code order according to a predetermined rule based upon at least one element of the selected code set.
