In receiving a radio block comprising a plurality of bursts, burst data is saved prior to demodulating each burst using an independent preliminary modulation technique decision. When a global modulation technique decision over the radio burst is formulated, if the preliminary modulation technique decision for one or more bursts disagrees, data associated with that burst may be retrieved and demodulated using the global modulation technique decision. In one embodiment, the mismatching burst is erased and decoding over the block is attempted, with the second demodulation being performed only if a decoding metric indicates decode errors. In another embodiment, each mismatching block is re-demodulated as soon as a global modulation technique decision is formulated and a mismatch to the preliminary modulation technique decision is detected. In both embodiments, an increase in the number of soft bits improves decoder performance.
