26、ard (dow): 30 November 200 1 Scope The present document specifies the minimum performance parameters for terrestrial fixed service digital radio communications equipments operating in the 13 GHz, 15 GHz and 18 GHz frequency bands. Digital Radio Relay Systems (DRRS) are used for point-to-point connec

27、tions in local, regional and national networks at data rates between 2 Mbitls and 34 Mbitls. As harmonized channel spacings lower than 13,75 MHz are not available in the 18 GHz frequency band at the drafting date of the present document, capacities lower than 2 x 8 Mbitls are consequently not consid

28、ered in this frequency band. However the present document can be considered as a guideline when national frequency plans based on a 3,5 MHz channel spacing exist. Systems considered in the present document are able to respect ITU-R Recommendation national or international grade performance objective

29、s, i.e. ITU-R Recommendations F. 1 189-1 9 for national, ITU-R Recommendation F. 1092-1 8 for international and ITU-T Recommendation G.826 ll. Maximum hop lengths of about 35 km are normally achievable according to the considered frequency bands. The parameters to be specified fall into two categori

30、es: a) those that are required to provide compatibility between channels from different sources of equipment on the same route, connected either to: - separate antennas; or to - separate polarizations of the same antenna. b) parameters defining the transmission quality of the proposed system. The pr

31、esent document deals with Radio Frequency (RF) and baseband characteristics relevant to low and medium capacity Plesiochronous Digital Hierarchy (PDH) transmission. Antennalfeeder system requirements are covered in EN 300 833 IS. As the maximum transmission rate in a given bandwidth depends on syste

32、m spectral efficiency, different classes are defined: Class 1: equipment based on a minimum 4-state modulation scheme (e.g. 4-FSK, 4-QAM, or equivalent). Class 2: equipment based on a minimum 16-state modulation scheme (e.g. 16-QAM, or equivalent). Safety aspects are outside the mandate of ETSI and
