二维QAM旋转不变TCM设计方法的研究
RESEARCH OF THE DESIGN METHOD FOR ROTATIONALLY INVARIANT TRELLIS CODES WITH 2-D QAM
【摘要】 本文在L.F.Wei(1984)的工作基础上,定义了格状码格状图的一般结构,讨论了二维QAM星座的旋转不变格状码的性质,给出了其全部不等价信号安排,从而可以方便地设计旋转不变格状码。
【Abstract】 Based on L. F. Wei’s work (1984), the generalized trellis diagram oftrellis codes is defined, then the properties of rotationally invariant trellis codes with two-dimensional QAM constellations are discussed, and all the unequivalent signal assignments are given. Finally, rotationally invariant trellis codes are designed easily.
