Abstract
A wideband transceiver for a gateway is presented. The wideband transceiver may interface with the gateway's processors over an interface that carries data encapsulated in baseband frames. The wideband transceiver may comprise a modulator and a high power amplifier and may improve a transmitted signal quality and may utilize a wideband for wireless communications, for example, for a satellite communication system.
Claims20
An apparatus comprising:
- an interface configured to receive at least one frame and to remove a first header from the at least one frame to produce at least one stripped frame;
- a modulator configured to:
- associate, based on a carrier identifier included in the at least one stripped frame, an adaptive coding and modulation (ACM) tagged frame included in the at least one stripped frame with a carrier corresponding to the carrier identifier;
- extract a baseband frame included in the ACM tagged frame;
- and
- modulate the baseband frame on to the carrier to generate a modulated signal;
- a filter configured to generate, based on the modulated signal, a filtered baseband signal;
- and
- a transmitter configured to transmit a radio frequency (RF) signal corresponding to the filtered baseband signal.
6 more elements
A gateway comprising:
- one or more Internet Protocol encapsulators (IPEs);
- and
- at least one transceiver configured to interface, via a first interface, with the one or more IPEs, wherein:
- the at least one transceiver receives, from at least one IPE of the one or more IPEs, at least one frame comprising at least one adaptive coding and modulation (ACM) tagged frame and a carrier identifier,
- the at least one ACM tagged frame comprises at least one baseband frame and an ACM information field, and
- the at least one baseband frame comprises data to be transmitted over a satellite link.
3 more elements
A method comprising:
- receiving, by a wireless transceiver and via a first interface, at least one frame;
- determining, based on removing a first header from the at least one frame, at least one stripped frame;
- associating, based on a carrier identifier included in the at least one stripped frame, an adaptive coding and modulation (ACM) tagged frame included in the at least one stripped frame with a carrier corresponding to the carrier identifier;
- extracting a baseband frame included in the ACM tagged frame;
- and
- modulating the baseband frame on to the carrier to generate a modulated signal;
- generating, based on the modulated signal, a filtered baseband signal;
- and
- transmitting a radio frequency (RF) signal corresponding to the filtered baseband signal.
