22、mum performance parameters for terrestrial digital fixed service radio communications equipments operating in the 15 GHz to 38 GHz frequency band intended to be used for point-to-point connections in local and regional networks at data rates between 2 x STM-1 (transported by one carrier) and 4 x STM

23、-1 or STM-4 (transported by two 2 x STM-1 carriers). Harmonized channel spacings of 56 MHz are not available in frequency bands below 15 GHz at the drafting date of the present document. However, the present document can be considered as a guideline where national frequency plans allow the use of 55

24、/56 MHz channel spacing in other frequency bands, or where an allocation of two contiguous 28 MHz channels is possible. The maximum transmission rate in a given bandwidth depends on system spectral efficiency, a single equipment class is defined: Class 5: equipment spectral efficiency based on typic

25、ally 128-states modulation scheme (e.g. 128-QAM, or equivalent). However, for addressing different market requirements, the systems are further subdivided in two grades: a) Adjacent Channel Alternate Polarization (ACAP as class 5a). b) Adjacent Channel Co-Polarization (ACCP or CCDP as class 5b). The

26、 above classes are indicative only and do not imply any constraint to the actual modulation format, provided that all the requirements in the present document are met. Examples of the spectrum usage are given in figure 1 The 4 x STM-1 or STM-4 connection is achieved by two 2 x STM-1 carriers. The tw

27、o carriers can be arranged in three configurations: a) b) c) Adjacent Channel Alternate Polarization for which ACAP, class 5a is applicable. Adjacent Channel Co-polarization for which ACCP, class 5b is applicable. Co-Channel Dual Polarization for which CCDP, class 5b is applicable. For this configur

28、ation, XPIC may be used. Examples of the three spectrum usage of a 4 x STM-1 or STM-4 system are given in figures la, lb, and IC. A 2 x STM-1 system is achieved by using one single carrier in 55/56 MHz from any of the configurations in figure 1; the system shall comply with the relevant spectrum eff
