摘要
研究了一种新的格状编码调制技术——多重格状编码调制(MTCM).总结了系统化设计 MTCM 的步骤;着重分析了多重 MPSK 方案的 d_(free)性能,并对常规MTCM 进行了有意义的推广,使其在实现非整数比特传输等方面具有优越性和灵活性.
A systematic design procedure for a new trellis modulation scheme refered to mul- tiple trellis coded modulation is summarized.The performance of multiple trellis coded MP- SK modulation measured by d(?)ree is studied.Then a new generalized multiple trellis coded modulation with the advantage of flexibility in achieving a varity of fractional information rates is described,and several schemes are discussed.
