RESEARCH OF THE DESIGN METHOD FOR ROTATIONALLY INVARIANT TRELLIS CODES WITH 2-D QAM
-
摘要: 本文在L.F.Wei(1984)的工作基礎(chǔ)上,定義了格狀碼格狀圖的一般結(jié)構(gòu),討論了二維QAM星座的旋轉(zhuǎn)不變格狀碼的性質(zhì),給出了其全部不等價信號安排,從而可以方便地設(shè)計旋轉(zhuǎn)不變格狀碼。

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. -
