13、ectromagnetic compatibility and Radio spectrum Matters (ERM). The present document handles the spectrum compliance of Forward Link Only air interface specification (TS 102 589 i.1) with DVB-T Harmonized Standard EN 302 296 i.2. Introduction An introduction to the Forward Link Only air interface can
14、be found in informative annex A of TS 102 589 i.1. Additional details on the derivation of the baseline parameters for 8 MHz, 7 MHz, 6 MHz and 5 MHz RF channel bandwidths is provided in annex B of TS 102 589 i.1. ETSI ETSI TR 102 699 V1.1.1 (2009-07) 51 Scope The present document provides an analysi
15、s of the spectrum compatibility of Forward Link Only air interface as specified in TS 102 589 i.1 with DVB-T in the bands addressed in the scope of EN 302 296 i.2. In accordance with the corresponding Work Item description, the present document reviews test methodology, test set configurations, and
16、measurement results for Forward Link Only compliance with respect to a DVB-T waveform and ETSI critical mask for adjacent channel interference. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

The logical methodology to perform such analysis
25、is to follow the methods given in clause 4 of Harmonized Standard EN 302 296 i.2 for demonstrating the compliance with the technical requirements specified in that clause. These requirements are intended to cover the provisions of article 3.2 of Directive 1999/5/EC (R&TTE Directive) i.3 which addres
26、ses the effective use of the spectrum allocated to terrestrial/space radio communications and orbital resources in such a way to avoid harmful interference. In particular, clause 4.2 on “Antenna port measurements“ is considered in the present document. In the following, results on the measurements o
27、f “Spurious emissions“ (clause 4.2.1) and “Out-of-band emissions“ (clause 4.2.2) for the transmitter given in i.4 are presented. This transmitter is referred to as “the typical commercial transmitter“ in the rest of the present document. 4.2 Results 4.2.1 Spurious emissions The main scope of the pre
28、sent document is to present test methodology, test set configurations and measurement results for Forward Link Only compliance with respect to a DVB-T waveform and ETSI critical mask for adjacent channel interference. However, it is useful and informative to present as well results which demonstrate
29、 Forward Link Only compliance with respect to the spurious emissions specified in EN 302 296 i.2. This clause is addressing this subject. The methodology used to measure the spurious emissions is according to clause 4.2.1 of EN 302 296 i.2. The results for the typical commercial transmitter and 8 MH
30、z channel, in the frequency range 862 MHz, were compared to the limits for this frequency range given in table 4.1 of EN 302 296 i.2 and are shown in figure 1.

Table 1 shows these limits by applying the correction factor -1,25 dB required to convert th

39、smitter with digital TV systems operating in the bands addressed in the scope of EN 302 296 i.2. The assessment criterion is the comparison of Forward Link Only out of band emissions with those of DVB-T. For this purpose, the compliance of Forward Link Only transmitter with Harmonized Standard EN 30
40、2 296 i.2 is used as the methodology to show the spectrum compatibility. The rationale for this approach is the fact that requirements defined in a Harmonized Standard are intended to cover the provisions of article 3.2 of R&TTE Directive in terms of effective use of spectrum in such a way to avoid
41、harmful interference. On the other hand, a full compliance with all requirements of the EN 302 296 i.2 is required only for placing digital TV radio equipments on the market. However this is not the goal of the present document, rather to demonstrate spectrum compatibility in the context of the corr
42、esponding Work Item description. Therefore, a compromise approach, as described in the following, was selected in order, on one hand, to reduce the number of required measurements and, on the other hand, to demonstrate the compliance with the most essential requirements specified in EN 302 296 i.2.
43、Out-of-band emission, which is technology dependent, was considered in the corresponding Work Item description as the core requirement for the verification of spectrum compatibility. Figure 3 demonstrates this fact, where the out of band emissions of Forward Link Only are compared to those of DVB-T.
44、 It can be identified from this figure that the only place that there is a discernable difference between the results for the two technologies is in frequency separations from the centre frequency in the range of 3,81 MHz to 4,2 MHz, where frequency response of Forward Link Only is slightly narrower
45、. The compliance of Forward Link Only transmitter with the out-of-band emission requirements of digital TV in EN 302 296 i.2 was shown for the typical commercial transmitter in clause 4.2.2 of the present document.

46、uency response with that of DVB-T The spurious response test is not requested in the corresponding Work Item description. This is due to the fact that it is unrelated to the technology and is a characteristic of the transmitter filter. However, it was considered as useful and informative to present
47、results which demonstrate Forward Link Only compliance with respect to the spurious emissions specified in EN 302 296 i.2. Therefore, the compliance of Forward Link Only spurious emissions with the limits specified for DVB-T in EN 302 296 i.2 was not tested for the entire frequency range in table 4.
48、1 EN 302 296 i.2, but in the frequency range above 862 MHz. The compliance of Forward Link Only transmitter with the spurious emission requirements of digital TV was demonstrated for the typical commercial transmitter in clause 4.2.1 of the present document.
