Abstract
A technique is provided for implementing adaptive thresholds associated with HS-SCCH detection schemes; and when applied to any HS-SCCH detection scheme, the resulting false alarm probability curves are more robust to amplitude variations of the different shared control channels. The technique has low computational complexity and low storage requirements for the estimator. Such lower complexity detection schemes have been found to outperform more complex schemes when adaptive thresholds are applied.
Claims7
A high-speed shared control channel (HS-SCCH) detection method comprising the steps of:
- estimating an amplitude value associated with a received signal on a shared control channel (SCCH);
- and
- scaling a desired threshold value by the estimated amplitude value to generate an adaptive threshold value there from, such that the adaptive threshold value is substantially robust to amplitude variations associated with at least one SCCH.
