Methods and apparatus for generating composite code sequences

An apparatus, comprising:

• a database to store first, second, and third component code sequences;
• and
• a processor, based on the component code sequences obtained from the data base, to:
• determine a first number of samples to be contributed into a first unit duration of a composite code sequence from the respective first, second, and third component code sequences;
• based on the first number of samples determined, randomly select the first number of samples from the respective ones of the first, second, and third component code sequences to enable the selected samples to more accurately represent the respective ones of the first, second, and third component code sequences;
• and
• compile the selected samples into the first unit duration of the composite code sequence by interspersing a sample from the first component code sequence between samples from the second component code sequence or between samples from the third component code sequence.

A machine-readable storage device or storage disk comprising instructions which, when executed, cause a machine to at least:

• determine a first number of samples to be contributed into a first unit duration of a composite code sequence from respective first, second, and third component code sequences;
• based on the first number of samples determined, randomly select the first number of samples from the respective ones of the first, second, and third component code sequences to enable the selected samples to more accurately represent the respective ones of the first, second, and third component code sequences;
• and
• compile the selected samples into the first unit duration of the composite code sequence by interspersing a sample from the first component code sequence between samples from the second component code sequence or between samples from the third component code sequence.
