| Abstract(in English) | Unequal error protection(UEP)codes have the multilevel error capability for each information symbol to be decoded. In this paper, we constructed UEP convolutional codes by evaluating the conditional weight distributions. The weight distributions are defined newly, and are computed by using the transfer functions of time-varying trellis structures. The best UEP convolutional codes having time-varying encoder(i.e.punctured convolutional encoder)from the viewpoint of the weight distributions are listed. |
