INTRODUCTION The following tables provide information on fixed service system parameter
3、s for use in initiai sharing studies. The tables were compiled from information supplied by members of CEIT Project Team SE19. The table format follows that of ITU-R Recommendation F 758, with systems being identified by moduiation type and system capacity, and systems grouped together by frequency
4、band. The introduction to Recommendation P758 contains information on the use of such tables, together with basic considerations in the development of sharing criteria. It gives advice on the basic transmitter and receiver characteristics required for interference evaluation and caicuiations for fre
