A special construction method for parallel concatenated trellis coded modulation, namely staggered trellis coded modulation, is presented. This coding scheme is similar to that of the recently introduced binary laminated turbo codes and it comprises a convolutional structure due to an additional block-wise memory. The encoder and a possible decoder for this new code construction is presented and the performance is compared to that of conventional parallel concatenated trellis coded modulation showing a significant improvement for comparable code parameters.
