1、QUESTION ITU-R 230-2/5*,*Sofware defined radios(2000-2003-2007)The ITU Radiocommunication Assembly,consideringa) that considerable research and development has been done on Software Defined Radio(SDR) design;b) that SDRs may offer design and operational versatility and flexibility in mobile radiosys
2、tems;c) that SDRs may facilitate spectrum efficiencies in complex mobile radio configurations;d) that SDRs offer intersystem interoperability in disaster and emergency situations;e) that SDRs may facilitate the regional and global harmonization of wirelesscommunications;f) that SDRs may provide for
3、improve manufacturing economies of scale;g) that SDR design can provide users with more operational features;h) that Recommendations on SDR design would be complementary to other ITU-RRecommendations on mobile telecommunications,decides that the following Questions should be studied1 What should the
4、 appropriate ITU-R definition for SDR be?2 What are the key technical characteristics that are associated with the design andapplication of SDR?3 What frequency band considerations are important to the application of SDR?4 What special interference considerations may be required in SDR applications?
5、5 What are the operational implications of SDR to mobile radio systems?6 What technical considerations are necessary to insure conformance withITU Recommendations and Radio Regulations?further decides1 that the results of the above studies should be included in one or more Recommendations,Reports, or Handbooks;2 that the above studies should be completed by the year 2010.Category: S2_* This Question should be brought to the attention of Radiocommunication Study Groups 1, 6 and 9.* Former Question ITU-R 230-2/8.Formatted: English (U.K.)
