高效數(shù)字調(diào)制VMSK的錯(cuò)覺
The vmsk modulation delusion
-
摘要: Walker提出了一種高效率的數(shù)字調(diào)制方案VMSK調(diào)制,根據(jù) Walker的分析,它的頻帶利用率可以達(dá)到 30bit/(sHz),而且沒有能量損失。該文從工程和信號(hào)處理的角度分析了這種調(diào)制,得到了一個(gè)非??上У慕Y(jié)果,這種調(diào)制并沒有所說的性能。

Abstract: H. R. Walker presented a high spectral efficiency modulation (VMSK). It can reach 30 bit/(sHz) simply without loss of SNR in his analysis. There are papers introduce this technology in China too. But, through deeply analysis based on the engineering point, a very regrettable conclusion is obtained, i.e, this technology is a beautiful rainbow! -
