design of ump frequency modulations

... with symmetrical XC matrix, again excluded by XOR V Design of ump frequency modulations In this section, we consider non-linear frequency modulations that naturally possess multidimensional alphabets, ... we will find that existence of catastrophic parameters is much more detrimental than not being UMP In case of frequency modulations (without catastrophic parameters), UMP alphabets are important ... bi-orthogonal modulations with XOR are UMP 4) Non-linear frequency modulations FSK and fullresponse continuous phase modulation (CPM) naturally comprise multiple complex dimensions needed to obey UMP condition...
