摘要：
High rate binary coset codes are investigated. The binary coset (BC) code is a binary convolutional code with parallel path. In our previous research of concatenated trellis-coded modulation (TCM) scheme, we have found that the effective minimum distance of inner code is more important than the minimum free distance when TCM is used as inner code. In this paper, for inner code, we construct the high rate BC codes by maximizing the effective minimum distance. With the new inner codes, we can decrease the decoding complexity of the inner code compared with conventional best convolutional code while maintaining the overall decoding performance.
