Abstract
A satellite receive unit for receiving a plurality of satellite signals from a plurality of satellites, the satellite receive unit including: a plurality of low noise blocks each for receiving one or more of the satellite signals and providing a received signal, at least one of the low noise blocks receiving a plurality of the satellite signals; and a satellite signal processing unit including a plurality of branches each arranged to receive a corresponding one of the received signals from the plurality of low noise blocks, each branch having a multiplier arranged to weight the received signal by multiplying by a corresponding coefficient; and an adder arranged to add the weighted signals of each branch to generate an output satellite signal.
Claims15
A satellite receive unit for receiving a plurality of satellite signals from a plurality of satellites, the satellite receive unit comprising:
- a plurality of low noise blocks each for receiving one or more of said satellite signals and providing a received signal, at least one of said low noise blocks receiving a plurality of said satellite signals;
- and
- a satellite signal processing unit comprising:
- a plurality of branches each arranged to receive a corresponding one of the received signals from the plurality of low noise blocks, each branch comprising a multiplier arranged to weight the received signal by multiplying by a corresponding coefficient;
- and
- an adder arranged to add the weighted signals of each branch to generate an output satellite signal.
A satellite system comprising:
- at least two satellites in geostationary orbit separated from each other by less than 6 degrees of longitude;
- and
- a decoder arranged to receive a combined signal comprising satellites signals from each of said satellites having at least partially overlapping frequency bands, and to extract one of said satellite signals from said combined signal.
A method of receiving a plurality of satellite signals from a plurality of satellites comprising:
- receiving by each of a plurality of low noise blocks one or more of said plurality of satellite signals, at least one of said low noise blocks receiving a plurality of said satellite signals;
- and
- receiving, by each of a plurality of branches, a corresponding signal from the plurality of low noise blocks, and multiplying the signal by a corresponding coefficient to weight each signal;
- and
- adding by an adder the weighted signals of each branch to generate an output satellite signal.
