Datum Systems brings advanced Sharp Carrier Filter Roll-Off Technology

Datum Systems brings advanced Sharp Carrier Filter Roll-Off Technology

Datum Systems now offers improved Low Excess Bandwidth (Alpha) Filtering, in its new M7 line of Modems that allow carrier spacing at frequency offsets below 10% of the symbol rate.  Datum currently offers down to a 5% Alpha, which means that carriers can be spaced at 1.05 times the symbol rate instead of the historical […]

Calcula Ahorros en Ancho de Banda con Filtros Roll-off Más Abruptos

Calcula Ahorros en Ancho de Banda con Filtros Roll-off Más Abruptos

Con modems satelitales avanzados alcanzando los límites de eficiencia espectral y flexibilidad de configuración, los esfuerzos de la industria se han recientemente enfocado en reducir el factor de filtros roll-off (espaciamiento entre portadoras) lo más posible, sin que esto impacte en la capacidad de corrección de errores. La combinación de filtros más verticales y codificación […]

Calculate Bandwidth Savings with Sharper Roll-off Filters

Calculate Bandwidth Savings with Sharper Roll-off Filters

With advanced satellite modems closely approaching the limits of spectral efficiency and configuration flexibility, industry efforts have more recently focused on reducing the transmit and receive filter roll-off factor (carrier spacing) by as much as possible without impacting modems error correction capability.  The combination of shaper roll-off filters and advanced FEC coding (like granular LDPC) […]

Calculate SCPC Savings in 5 Simple Steps

Calculate SCPC Savings in 5 Simple Steps

Calculating satellite capacity savings when considering two options of SCPC modems can be done in two ways: Link Budgets (LBs): Redo link budgets based on the new modem performance curves. The new LBs will allow the comparison of scenarios “A” and “B”. Comparison Calculator: A very close approximation can be obtained quickly without redoing LBs. […]
