Abstract:
This paper introduces a communication system with typically wireless transmission, with SISO convolutional decoding using predefined reliability values at input of the SISO decoder. “Dummy” bits are stuffed into the information which is to be transmitted over a noisy channel and SISO decoded. Stuffed bits have to be known at the receiver, so that their reliability values can be defined at the input of the SISO decoder, before the information is to be decoded. The results of simulations have been presented and discussed, showing how differ-ent number of stuffed bits has to be chosen depending on the length of information.
