Foreword This European Standard (Telecommunications series) has been
20、produced by ETSI Technical Committee Transmission 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 require
21、d to interwork at radio frequency (i.e. no common 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 rela
22、y equipment and associated interfaces. The requirements for multiplex, network management and antenna/feeder equipment may be addressed elsewhere. This new version modifies only class 5b spectrum mask giving more allowance for practical implementations, without modif$ng any other requirements, and p
23、roposed design objectives for class 5a BER versus RSL.

The channel spacing between adjacen
25、t Co-polar channels shall be 55 MHz or 27,5 MHz. Operation in the Adjacent Channel Co-Polarization (ACCP) mode for class 4 systems and class 5 systems as defiied below with orthogonal polarizations or in the alternated cross-polar mode is foreseen. Additionally for class 4 systems, operation in the
26、Co-Channel Dual Polarized (CCDP) mode with orthogonal polarization is also foreseen. The 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 freq
27、uency range 17,7 GHz to 19,7 GHz and contains a revision from the previous version, in the 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
28、the present document, refer to new annex C and related categories of equipment classes of 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 examp
29、les of the spectrum usageinfigures 1.laandl.lb: - I II I II Figure 1 - technical specifications 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 Transpo
30、rt Module, level 1 (STM-1). The parameters to be specified fall into two categories: 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 - - separate polarizations of the same antenna;
31、 or one polarization of one antenna at a frequency separation of 110 MHz or more, enabling, in addition for class 4 equipment only, intenvorking of different manufacturers equipment at the same Radio Frequency (RF) branching; this category also includes parameters providing compatibility with the ex
32、isting radio-relay network. - b) parameters defining the transmission quality of the proposed system. The standardization deals with RF and baseband characteristics. Antenna/feeder system requirements are covered in EN 300 833 33. Two possible baseband interfaces for SDH systems have to be considere
33、d: one for STM-1 and another for 140 Mbit/s signals. The present document does not contain aspects related to test procedures and test conditions, however they are to be found in EN 301 126-1 19. ETSI 7 ETSI EN 300 430 VI .4.1 (2002-07) As the maximum transmission rate in a given bandwidth depends o
34、n systems spectral efficiency, different classes are defined: - class 4: equipment spectral efficiency based on typically 16 or 32-states 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,
35、 128-QAM, or equivalent). - The 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. Safety aspects will not be considered in the present document. However compliance to EN 60950-1 28 wi
