Foreword
19、 This European Standard (Telecommunications series) has been produced by ETSI Technical Committee Transmission and Multiplexing (TM). The present document specifies the minimum performance parameters for radio equipment operating in the frequency ranges as detailed in clause 4.1.1. The former title
20、of the present document was “Transmission and Multiplexing; Digital Radio Relay Systems; Parameters for DRRS for the transmission of digital signals operating at 55 GHz“. National transposition dates Date of adoption of this EN: Date of latest announcement of this EN (doa): Date of latest publicatio
21、n of new National Standard or endorsement of this EN (dop/e): Date of withdrawal of any conflicting National Standard (dow): 13 July 2001 3 1 October 200 1 30 April 2002 30 April 2002 ETSI 6 ETSI EN 300 407 V1.3.1 (2001-08) 1 Scope The present document specifies the minimum performance parameters fo
22、r terrestrial digital fixed service radio communications equipments operating in the 55 GHz frequency band and is a complete revision of the existing ETS 300 407 8 specification in the areas of - introduction of unique system type codes for regulatory reference to the various system types detailed i
23、n the present document, refer to new annex C (normative) and related categories of equipment classes of spectral efficiency; additional systems with higher spectrum efficiency in the new classes 1 to 4; - - removal of Analogue services; - - digital services restricted to frequency division duplex (F
24、DD) operation only; technical specifications relevant to the EMC Directive, detailed in annex B (normative); - specific antenna radiation patterns (now superseded by EN 300 833 12). Digital systems are intended to be used for point-to-point connections in local and regional networks at data rates be
25、tween 2 Mbit/s and Synchronous Transport Module, level 1 (STM-1). Digital systems considered in the present document will be able to meet the error performance objectives of the ITU-R national portion of the reference path, i.e. ITU-R Recommendation F. 1 189 191 and the error performance objectives
26、detailed in ITU-T Recommendation G.826 26. 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 to separate antennas; b) parameters defining the transmission qual
27、ity of the proposed system. The present document deals with Radio Frequency (RF) and baseband characteristics relevant to low, medium and high capacity Plesiochronous Digital Hierarchy (PDH) transmission systems, and STM-O and STM- 1 Synchronous Digital Hierarchy (SDH) transmission systems. Antenna/
28、feeder system requirements are covered in EN 300 833 12. 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 3. As the maximum transmission rate in a given bandwidth depends on system spectral efficiency, different
29、 equipment classes are defined: Class 1: equipment spectral efficiency based on typically 2-states modulation scheme (e.g. 2-FSK, Gaussian Minimum Shift Keying (GMSK) with discriminator detection, or equivalent); equipment spectral efficiency based on typically 4-states modulation scheme (e.g. 4-FSK
30、, 4-QAM, or equivalent); equipment spectral efficiency based on typically 8-states modulation scheme (e.g. 8PSK or equivalent); Class 2: Class 3: Class 4: equipment spectral efficiency based on typically 16 or 32-states modulation scheme (e.g. 16- QAM, 32-QAM, or equivalent). The above classes are i
31、ndicative 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 are not considered in the present document. However compliance to EN 60950 34 will be required to comply with the 1999/5/EC Directive (R
