Data processing method that selectively performs error correction operation in response to determination based on characteristic of packets corresponding to same set of speech data, and associated data processing apparatus

摘要

A data processing method for performing data processing on wireless received data and an associated data processing apparatus are provided, where the data processing method is applied to an electronic device. The data processing method includes the steps of: wirelessly receiving a plurality of packets corresponding to a same set of speech data from another electronic device; and selectively performing error correction operation on at least one of the plurality of packets to obtain the set of speech data, wherein whether to perform the error correction operation is determined according to at least one characteristic of the plurality of packets. More particularly, the error correction operation is selectively performed for at least one scenario of a timing critical scenario and a re-transmission limited scenario.

1. A data processing method applied to an electronic device, the method comprising the steps of:
wirelessly receiving a plurality of packets corresponding to a same set of speech data from another electronic device; and selectively performing error correction operation on at least one of the plurality of packets to obtain the set of speech data, wherein whether to perform the error correction operation is determined according to at least one characteristic of the plurality of packets, wherein the error correction operation comprises Cyclic Redundancy Check (CRC) error correction, and the step of selectively performing the error correction operation on at least one of the plurality of packets to obtain the set of speech data further comprises:
checking if at least two packets of the plurality of packets are CRC-incorrect, andif yes, performing the CRC error correction operation on at least one of the packets to obtain the set of speech data, wherein the step of performing the CRC error correction operation on at least one of the packets to obtain the set of speech data further comprises:
modifying at least one potential error bit of at least one of the two packets to obtain a trial packet; andchecking whether the trial packet is CRC-correct in order to obtain the set of speech data.
