摘要

在1977年Imai等人提出了使用多層編碼技術，它結合了二位元區段碼與信號空間的分割。調變碼使用多層的方法來建立，我們稱之為多階層調變碼，此方法若適當地應用在區段碼調變，我們可以藉由選擇適當的組成碼得到任何我們想要的錯誤更正性能。但隨著碼長的增加，解碼的複雜度也會越來會大。在本篇論文中，我們將分割信號空間的觀念推廣至區段調變碼，而提出一項新的編碼系統，同時也作了模擬驗証。

Block-coded modulation codes are generally constructed from Hamming distance block component codes by using the multilevel coding method proposed by Imai and Hirakawa. The multilevel coding method is a powerful technique for constructing BCM (or TCM)codes systematically with arbitrarily large distance parameters for AWGN channels. The multilevel structure of the multilevel BCM codes allows the use of multistage decoding procedures the provide good tradeoff between error performance and decoding complexity. In this thesis ,we generalize the concept of set partitioning of a signal set to a block modulation code. A new coding system is proposed. Simulation results and analysis are given to verify the performance.
