Abstract

In this paper, a new class of punctured convolutional codes (PCCs) is presented, in which a PCC is obtained by punctUling a rate 1/2 periodically time-varying convolutional code (the "mother" code), where different phases within a petiod may have different memory sizes. In the new class, which encompasses all previous PCCs of rate greater than 1/2 ever published, the trellis complexity can be gradually increased resulting in a better distance spectrum at each new complexity increment, offering more flexibility on the choice of the complexity x petformance relationship.
