Systems and methods for detecting discontinuous transmission (DTX) using cyclic redundancy check results to modify preliminary DTX classification

A method of detecting whether a normal burst or a truncated burst is present in a received information signal, the method comprising:

• decoding the received information signal to obtain the received information and to produce at least one feature of the received information signal;
• cyclic redundancy checking the received information that is decoded;
• and
• classifying the received information signal as containing a normal burst or a truncated burst based upon the at least one feature of the received information signal and the cyclic redundancy checking.

A system for detecting whether a normal burst or a truncated burst is present in a received information signal, the system comprising:

• a decoder that is configured to decode the received information signal to obtain the received information and to produce at least one feature of the received information signal;
• a preliminary classifier that is configured to preliminarily classify the received information signal as containing a normal burst or a truncated burst based upon the at least one feature, to obtain a preliminary classification;
• a cyclic redundancy checker that is configured to cyclic redundancy check the received information that is decoded;
• and
• a second stage classifier that is configured to further classify the received information signal as containing a normal burst or a truncated burst based upon the preliminary classification and whether the cyclic redundancy checking is valid, to obtain a further classification.
