<p>Enabling the joint detection and decoding of Uplink State Flag (USF) symbols. A method is provided that involves determining one or more residual error terms by jointly detecting and decoding in one or more bursts of a radio block 72. In some example embodiments, the one or more residual error terms are determined over a plurality of uplink state flag symbols in the one or more bursts that correspond to a plurality of available uplink state flag sequences 76. The method of this embodiment may also include determining a weighted error measure for each of the plurality of available uplink state flag sequences based on the one or more residual error terms 78. The uplink state flag value is determined based on the plurality of weighted error measures 80, which may comprise selecting the USF sequence based on the one with the smallest weighted error measure. The one or more residual error terms may be determined by compensating for the Inter-Symbol Interference (ISI) between the USF symbols and Training Sequence Code (TSC) symbols or other data symbols. Data is transmitted in accordance with the detected USF sequence 84, possibly when it is determined to have been detected reliably 82.</p> |
