ITU-R BO.1130-4 FRENCH-2001把1400-2700 MHz频段分配给广播卫星业务(BSS)(声音),用于车载式,便携和固定接收机进行数字卫星广播

There is an increasing interest worldwide for digital sound broadcasting to vehicular, portable and fixed receivers in the broadcasting-satellite service (BSS) (sound) bands allocated at the World Administrative Radio Conference for Dealing with Frequency Allocations in Certain Parts of the Spectrum (Malaga-Torremolinos, 1992) (WARC-92), and that several satellite-based digital sound broadcasting services for national and supra-national coverage are being considered. Developed for both satellite and terrestrial broadcasting applications in order to allow a common low-cost receiver to be used. Digital System B, originally proposed by Voice of AmericdJet Propulsion Laboratory (VONJPL), was designed to provide maximum efficiency on board a communications satellite. Digital System Ds, also known as the Worldspace system, is primarily designed to provide satellite digital audio and data broadcasting for fixed and portable reception. Digital System DH, also known as the hybrid satellite terrestrial Worldspace system, is designed to provide satellite digital audio and data broadcasting for vehicular, fixed and portable reception by inexpensive common receivers. Digital System E, also known as the ARIB (Association of Radio Industries and Businesses) system, is designed to provide satellite and complementary terrestrial on-channel repeater services for high-quality audio and multimedia data for vehicular, portable and fixed reception.

Digital System DH, also known as the hybrid satellite/terrestrial WorldSpace system, is designed to provide satellite digital audio and data broadcasting for vehicular, fixed and portable reception by inexpensive common receivers

ITU-R BS.1547 SPANISH-20011400-2700 MHz频率范围内车载式,便携式和固定式接收器的混合卫星地面数字声音广播系统的地面组件

The ITU Radiocommunication Assembly considering: a) that there is an increasing interest worldwide for terrestrial and satellite digital sound broadcasting (DSB) to vehicular, portable and fixed receivers in the frequency range 30-3 000 MHz for local, regional and national coverage; b) that the ITU-R has already adopted Recommendations ITU-R BS.774 and ITU-R BO.789 to indicate the necessary requirements for DSB systems to vehicular, portable and fixed receivers for terrestrial and satellite delivery, respectively; c) that by operating the broadcasting-satellite service (BSS) (sound) in an hybrid configuration the service objectives listed in b) above can be more adequately met; d) that Recommendations ITU-R BS.774 and ITU-R BO.789 recognize the benefits of complementary use of terrestrial and satellite systems, and call for a DSB system allowing a common receiver with common processing very large scale integration (VLSI) circuits and manufacturing of low-cost receivers through mass production; e) that Digital System D H described in Annex 2 meets most or all of the requirements of Recommendations ITU-R BS.774 and ITU-R BO.789, and that the system has been field tested and demonstrated in more than one country; f) that Digital System E described in Annex 3, meets most or all of the requirements of Recommendations ITU-R BS.774 and ITU-R BO.789, and that it has been field tested; g) that some systems included in Recommendation ITU-R BO.1130 have a terrestrial component which allows augmentation of the BSS (sound) part, hence creating a hybrid satellite/terrestrial system.

ITU-R F.1097-1-2000用来增强雷达系统和数字无线中继系统之间兼容性的干扰减小选择

The options listed below all depend on the condition that a particular radar installation has unequivocally been identified as the one causing the interference.

ITU-R F.1097-1 SPANISH-2000用来增强雷达系统和数字无线电中继系统之间兼容性的干扰抑制方案

The ITU Radiocommunication Assembly, considering that radar systems can produce interference to digital radio-relay systems (DRRSs) in some situations; that there are two coupling mechanisms by which radiated energy from radar stations may be coupled into radio-relay systems: radar spurious emission in the radio-relay bands; radio-relay system front-end overload (receiver desensitization) caused by the radar fundamental frequency; that the most desirable method of mitigating the interference may be to reduce the spurious emissions at the radar transmitter to a sufficiently low level; that some of the techniques employed by radio-relay system designers to enhance system performance are expected to reduce the susceptibility of these systems to interference from radar transmitters.

ITU-R INFORME M.2080 SPANISH-2006在4-10 MHz频段条件共享和使用的思考

In preparing the text for the draft CPM-07 Report, there were a number of input documents providing information on sharing conditions in the 4-10 MHz band. Although these documents have been taken into account in the revision of the draft CPM text for WRC-07 Agenda item 1.13, they contain valuable information for ITU-R studies in HF bands and have been used to create a new Report.
