Abstract:
1. A method in a communications receiver for decoding an encoded message sent from a remote transmitter, the method comprising: receiving first encoded bits corresponding to a first transmission of the encoded message; demodulating the first encoded bits to obtain first soft bits, each of the first soft bits having a sign value and a magnitude; decoding the first soft bits to obtain first decoded bits; receiving second encoded bits corresponding to a second transmission of the encoded message; demodulating the second encoded bits to obtain second soft bits, each of the second soft bits having a sign value and a magnitude; re-encoding the first decoded bits to obtain re-encoded bits, each of the re-encoded bits having either a positive or negative sign value; and determining sign values for modified soft bits corresponding to the encoded message, based on the sign values for the first soft bits, the sign values for the second soft bits, and the sign values for the re-encoded bits.
