News organizations relying on heavy use of satellite newsgathering technology may see some relief in the cost of space segment time if the laws of supply and demand and a new transmission technology from British Telecom (BT) have anything to do with it.
According to BT, it has developed new technology that triples the capacity of existing satellite communication links. The only new technology needed to deploy the capacity growth is required at ground stations. Therefore, upgrading existing systems is both straightforward and efficient.
The new modulation scheme draws on principles similar to those used in the signal transmitted by GSM phones, which delivers data over a modulation scheme consisting of two states. This new method uses multiple states, combined with partial response signaling. Its unique innovation lies in the design of the detection mechanism in the demodulator, which is based on symbol pattern recognition.
