全響應(yīng)CPM的減少狀態(tài)格狀圖
A REDUCED-STATE TRELLIS FOR FULL RESPONSE CPM
-
摘要: 連續(xù)相位調(diào)制(CPM)的最佳相干解調(diào)的譯碼性能取決于其最小平方歐氏距離。本文在不減少其最小平方歐氏距離的前提下,提出了全響應(yīng)CPM的減少狀態(tài)格狀圖,從而減少了Viterbi的譯碼復(fù)雜度。Abstract: The error performance of continuous phase modulation (CPM) with optimal coherent detection depends on the minimum squared Euclidean distance (MSED). In this paper, a reduced-state trellis for full response CPM is presented under the condition that the MSED is not reduced, and therefore the complexity of the Viterbi decoding is reduced.
