METHOD AND APPARATUS FOR DISTINGUISHING IN-BAND SIGNALING FROM USER DATA

摘要

A method for distinguishing between in-band signaling and user data transmissions of a communication system. The method includes the assignment of separate training bit sequences, one for in-band signaling transmissions and another for use data transmissions. During transmission, the training bit sequence associated with the type of transmission being sent is used as the training bit sequence. The method further includes the correlation of the received training bit sequence with both the training bit sequence assigned to in-band signaling and the training bit sequence assigned to user data. The training bit sequence having the highest correlation energy indicates the type of data contained in the communication transmission.
