Abstract
To detect a special burst sequence, a cross correlation (C) is compared to a square root of an estimated noise variance (σ) in conjunction with a threshold value (Th). In one aspect of the disclosure, the threshold value may include multiple threshold values. The multiple threshold values may be compared to an intensity or level of a special burst metric (C/σ) to facilitate determination of the special burst sequence. For example, when a special burst metric C/σ is greater than a second threshold value (Th2) it may be determined that a special burst sequence exists. However, when the special burst metric C/σ is greater than a first threshold value (Th1), but less than the second threshold metric (Th2), it may be determined that detection of a special burst is unclear. In this case, a TFCI value may be used to confirm whether a special burst is detected.
