The development and performance of a hardware-prototype multi-user detection (MUD) receiver for Inmarsat's Broadband Global Area Network (BGAN) is described. The MUD receiver is used to compensate increased adjacent channel interference due to reduced channel spacing and can simultaneously detect up to six bearers in a 200-kHz satellite subband. With this technique, the channel-spacing can be reduced...
In response to the Digital Britain Interim Report published in the UK in 2009, which mandated that every home must have access to broadband at 2Mbps, Avanti is developing HERCULES - a two satellite multi-spot beam Ka-band system covering the UK and Ireland. HERCULES is designed to provide Universal Service Commitment (USC) services in the UK to two million homes (10% of the population) and Next Generation...
The Maseng-Bakken model has shown interesting properties to model rain attenuation for Ka and Q/V broadband satellite systems. This paper derives the optimal rain attenuation predictor based on the Maseng-Bakken model. The optimal predictor is obtained by minimizing the mean square error between the rain attenuation and its estimate. We show that this predictor reduces to a bank of filters whose parameters...
