2 Technical Aspects for Digitalization of Radio broadcasting networks using the DRM standard Digital Radio in MW, LW and SW - DRM30 -
3 Comparison of reception distance AM vs DRM30 : Coverage efficiency The useful (information carrying) output from the DRM transmitter is likely to be greater than the sideband output from an AM transmitter operated with a typical average modulation rate. The fact that DRM is optimized for the RF channel should mean that greater coverage is achieved. A more useful measure of efficiency might be gained from looking at the coverage achieved for a given mains power level. Using this, DRM transmitters should routinely score higher than AM transmitters. EBU Tech 3330
4 Comparison of reception distance AM vs DRM30 : DRM : minimal field strength (dbuv/m) to get a BER of 1x10exp(-4) (ITU BS 1615) Modulation Protection Level No. Robustness (9kHz) 0 33,1 dbuv/m 16 QAM 1 35,2 dbuv/m 0 38,6 dbuv/m 1 39,8 dbuv/m 2 41,6 dbuv/m 64 QAM 3 43,2 dbuv/m Necessary field strength for DRM reception: min. usable field strength + 7 db (statistic variation of field strength over location and time) + 3 db reserve
5 Fieldstrength requirements for DRM Sideband power in AM versus DRM signal
6 DRM Minimum Transmitter (system) Requirements 1. MER > 30dB at transmitter output on the real antenna 2. Output power -7dB under Geneva 75 analogue allowance 3. ITU spectrum mask for out of band radiations met (ETSI EN and ITU SM.1541)
7 Minimum requirements for DRM Antennas VSWR < 1,05 at ± 5 khz from carrier VSWR < 1,10 at ± 10 khz from carrier Please refer to DRM Implementation Guide chapter 9.7.1
8 How can we get more coverage?
9 DRM DMOD3, Parameter settings, using Digital Power Enhancement Crest factor TX out [db] wanted CF=8.0dB wanted CF=8.3dB wanted CF=8.6dB wanted CF=8.9dB wanted CF=9.7dB limit for TRAM50 Crest Factor (CF) of DRM Signal as a Function of the DRM Power P DRM /P C [%]
10 DRM DMOD3, Parameter settings, using Digital Power Enhancement wanted CF=8dB wanted CF=8.3dB wanted CF=8.6dB wanted CF=8.9dB wanted CF=9.7dB limit MER as a Function of the DRM Power 34 MER [db] P DRM /P C [%]
11 DRM DMOD3, Parameter settings, using Digital Power Enhancement It is found that reducing the DRM signal s crest factor to lower values than 8dB violates minimum MER value of 30dB given in ETSI [1]. In order to have a MER safety margin, it is preferable to reduce the DRM crest factor only to 8.3dB. This gives an MER of 33dB with a DRM power of 41,5kW (=83% of the carrier power). Without applying any power enhancement technique, the MER value is well above 37dB.
12 DRM DMOD3, Parameter settings, using Digital Power Enhancement The Result TRAM 50 with 41,5KW DRM power
13 DRM DMOD3, Parameter settings, using Digital Power Enhancement What does it mean in practice? Existing transmitter power (Geneva 75) Allowed DRM output power (-7dB below Geneva 75) needed transmitter power for standard transmitters needed transmitter power using digital power enhancement 1000 kw 200 kw 400 kw 250 kw 200 kw 40 kw 100 kw 50 kw 100 kw 20 kw 50 kw 25 kw 20 kw 4 kw 10 kw 5 kw
14 DRM DMOD3, Parameter settings, using Digital Power Enhancement Comparison of reception distance AM vs DRM : Based on Tipaza in Algeria LW 252kHz (σ = 8 ms/m, εr = 4) Minimal field strength for AM reception: 64dBuV/m Transmitter power : 1. 5 MW (Geneva 75 Allocation) Coverage radius: 740 km Power consumption (m=0,35, η=87%): 1.84 MW Minimal field strength for DRM reception: 56dBuV/m Transmitter power : 400 kw Transmitted power DRM : 300 kw (using TSB Digital Power Enhancement ) Coverage radius : 760 km Power consumption : 365 kw
