Woven Trellis Coded Modulation with Inner Warp

In this work we address the woven code construction which was introduced for convolutional codes. We extend the inner warp approach for the general use of trellis coded modulation encoded via finite state machine encoders as inner code. In this case a lower bound on the minimum squared Euclidean distance of the overall woven trellis coded modulation can be stated based on the active distances of the outer code and the minimum squared Euclidean distance of the inner code
