碩士 === 國立臺北科技大學 === 電機工程系所 === 102 === By using the multilevel coset coding scheme, a long code can be constructed from several short codes in conjunction with coset codes so that the tellis complexity can be decreased. In this thesis, we propose a modified hierarchical binary multilevel coset coding scheme. The outer codes of the original multilevel coset coding scheme are also designed by using the multilevel coding to further reduce the trellis complexity. Moreover, interblock memory between adjacent blocks is added to increase the coding rate without decreasing the minimum Hamming distance. The simulation results show that the proposed scheme can achieve significant coding gains with low trellis complexity.
