Reed-Solomon Identifier

Reed-Solomon Identifier^[1] (kort RSID) er en digital kommunikationsprotokol primært for radioamatører, som muliggør automatisk identifikation af mange digitale protokoller (digimodes).^[2] RSID udsendes lige før en digital radioudsendelse - og kan også sendes som en afslutning af den digitale radioudsendelse. I modtagerenden kan RSID modtages og få softwaren til at dekode den digitale radioudsendelse som RSIDen indikerede. RSID formidler også den efterfølgende digitale radioudsendelses centerfrekvens.^[2]^[3]

RSID blev skabt november 2006 af den franske radioamatør Patrick Lindecker; kaldenavn F6CTE.^[1] RSID blev hovedsageligt udviklet med kortbølge for øje. Hvert et RSID-tal identificerer en modulationsform. Patrick Lindecker forvalter en tabel over RSID-tal og protokoller. RSID er udgivet som public domain.^[3]

En RSID varer 1,4 sekunder og benytter en båndbredde på 172 Hz. Kodningen benytter Reed-Solomon-fejlkorrektion. RSID sendes i MFSK-modulation. RSIDen kan afkodes med signal-til-støj-forhold ned til −16 Decibel, dvs at afkodningen virker for signaler langt under støjniveauet. RSIDens robusthed gør at RSIDen kan afkodes uden at den digital radioudsendelse kan afkodes hvis den kræver højere signal-til-støj-forhold end RSIDens.

RSID bliver understøttet af flere PC-programmer - fx:

MultiPSK af Patrick Lindecker. MultiPSK kan automatisk detektere RSID over en båndbredde på 192kHz.^[4]^[5]
FLDIGI for Linux und Windows.^[3]
