Quaternary constant-amplitude codes for multicode cdma
FREE-DOWNLOADKU Schmidt – Information Theory, research Transactions on, 2009 – Abstract—A constant-amplitude code is a code that reduces the peak-to-average power ratio (PAPR) in multicode code-division multiple access (MC-CDMA) systems to the favorable value 1. In this paper, quaternary constant-amplitude codes (codes over 4) of length 2m with
