Abstract:
1. A method to receive a speech signal transmitted over a wireless transmission link comprising coded channels, the method comprising: processing said signal using a digital signal processor having to execute two different types of tasks, a first type of task having higher priority and being executed in the foreground in real time without interruption, and a second type of task having lower priority and being executed in the background; equalization operations to compensate for signal distortion introduced by the transmission link in a signal burst, said equalization being arranged as a foreground task; and block decoding operations to perform channel decoding operation from the equalized signal bursts, said block decoding being arranged as a background task, wherein if one of the block decoding operations has not been executed before a predetermined time limit, it comprises at least one step of commanding said equalizer to discard one of the next burst equalization operations according to a predetermined rule, said discarded equalization operation being treated as a transmission error corrected using a redundancy of the signal.
