ABSTRACT:
A receiver for use in digital cellular communication systems determines the type of data transmitted without having to decode the data. Digital cellular communication systems typically use convolutional forward error correction (FEC) coding to allow for error detection and correction at the receiver. The type of encoding is different depending on whether voice data or control data is transmitted. In general, FEC coding is a redundant coding of the encoded data so that for a given encoding algorithm with FEC coding, there will be a limited number of valid code sequences less than the total possible number of code sequences for a transmission of the same number of bits. This characteristic is used to identify the type of encoding without decoding the received information. Consequently, decoding requirements are reduced to those corresponding to the active transmitting encoder, resulting in receiver complexity reduction.
