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. […]
