28、n and Multiplexing (TM). The present document contains the minimum technical requirements to ensure compatibility of products and conformance with radio regulations across ETSI member states. Radio terminals from different manufacturers are not required to intenvork at radio frequency (i.e. no commo

29、n air interface). However, terminals may be combined with other manufacturers equipment on a Radio Frequency (RF) branching network for operation on different polarizations. The present document defines the requirements of radio terminal and radio relay equipment and associated interfaces. The requi

30、rements for multiplex, network management and antennalfeeder equipment may be addressed elsewhere.

32、dow): 30 April 2003 1 Scope The present document specifies parameters for high capacity STM-1 digital radio-relay systems designed to operate in the 17,7 GHz to 19,7 GHz band. The channel spacing between adjacent co-polar channels shall be 55 MHz or 27,5 MHz. Operation in the Adjacent Channel Co-Pol

33、arization (ACCP) mode for class 4 systems and class 5 systems as defined below with orthogonal polarizations or in the alternated cross-polar mode is foreseen. Additionally for class 4 systems, operation in the Co-Channel Dual Polarized (CCDP) mode with orthogonal polarization is also foreseen. The

34、present document covers both single and multi-channel systems. The present document specifies the minimum performance parameters for terrestrial fixed service radio communications equipment operating in the frequency range 17,7 GHz to 19,7 GHz and contains a revision from the previous version, in th

35、e area of: - categorization of previously considered equipments into a new spectrum efficiency class 4; - introduction of unique system type codes for regulatory reference to the various system types detailed in the present document, refer to new annex C and related categories of equipment classes o

36、f spectral efficiency; - new spectrum efficiency class 5 for STM-1 capacity for 27,5 MHz Adjacent Channel Alternate-Polarization (ACAP as class 5a) and Adjacent Channel Co-Polarization (ACCP as class 5b), see examples of the spectrum usage in figures 1.1 a and 1.1 b: Figure 1 - technical specificati

37、ons relevant to the EMC Directive 30, detailed in annex B. The applications of these digital radio-relay systems are anticipated to be in the regional and access networks, at data rates of Synchronous Transport Module, level 1 (STM-1). The parameters to be specified fall into two categories: a) thos

38、e that are required to provide compatibility between channels from different sources of equipment on the same route connected either to: - separate antennas; or - separate polarizations of the same antenna; or - one polarization of one antenna at a frequency separation of 110 MHz or more, enabling,

39、in addition for class 4 equipment only, interworking of different manufacturers equipment at the same Radio Frequency (RF) branching; - this category also includes parameters providing compatibility with the existing radio-relay network. b) parameters defining the transmission quality of the propose

40、d system. The standardization deals with RF and baseband characteristics. Antennalfeeder system requirements are covered in EN 300 833 33. Two possible baseband interfaces for SDH systems have to be considered: one for STM-1 and another for 140 Mbitls signals. The present document does not contain a

41、spects related to test procedures and test conditions, however they are to be found in EN 301 126-1 19. As the maximum transmission rate in a given bandwidth depends on systems spectral efficiency, different classes are defined: - class 4: equipment spectral efficiency based on typically 16 or 32-st

42、ates modulation scheme (e.g. 16-QAM, 32-QAM, or equivalent); - class 5: equipment spectral efficiency based on typically 64 or 128-states modulation scheme (e.g. 64-QAM, 128-QAM, or equivalent). The above classes are indicative only and do not imply any constraint to the actual modulation format, pr

43、ovided that all the requirements in the present document are met. Safety aspects will not be considered in the present document.
