A multi-mode mobile wireless communications device architecture () including an application layer (), a services layer () interfacing the applications layer, a multi-mode layer () interfacing the service layer, and a hardware layer () interfacing the multi-mode layer. The multi-mode layer includes first and second interoperable radio access technologies, for example W-CDMA UMTS and GSM/GPRS technologies.

A fast pattern correlator and method comprising received bitstream data blocks split into estimation blocks and correlation blocks. Correlation blocks are extracted and compared to an expected pattern using a correlation part starting location estimator and correlator. The number of bit errors resulting is compared to a predetermined maximum in a threshold comparator. Extracting the correlation blocks includes indexing consecutive estimation blocks using an estimation part correlation table and predicting consistent correlation block starting locations. The correlation blocks are correlated with the expected pattern to produce an exclusive-OR result, which, used with a bit-error table, can be used to find a number of bit errors in the correlation.
