Abstract
A method of evaluating the usage in a received signal of codes from a tree of codes that can be used to orthogonalise communications signals, the method including testing to determine if a given code is in use in the received signal and deducing from the result and from the tree structure the need to test in the received signal for the use of the codes in the portion of the tree depending from said given code. The invention also includes corresponding apparatus and software.

1-13. (canceled)
A method of evaluating usage in a received signal of codes from a tree of codes adapted for use to orthogonalise communications signals, the method comprising:
- testing to determine if a given code is in use in the received signal;
- and
- analyzing the testing and the tree to determine if a second testing of the received signal for additional codes in a portion of the tree depending from the given code is required.
An apparatus for evaluating usage in a received signal of codes from a tree of codes adapted for use to orthogonalise communications signals, the apparatus comprising:
- means for testing to determine if a given code is in use in the received signal;
- and
- means for analyzing the testing and the tree to determine if a second testing of the received signal for additional codes in a portion of the tree depending from the given code is required.
A computer readable medium containing at least one code for evaluating usage in a received signal of codes from a tree of codes adapted for use to orthogonalise communications signals, which when executed by a computer causes the computer to execute the following steps:
- testing to determine if a given code is in use in the received signal;
- and
- analyzing the testing and the tree to determine if a second testing of the received signal for additional codes in a portion of the tree depending from the given code is required.
