Patent ID: 7620127

Claim:
A high availability digital radio architecture, comprising: a first analog interface subsystem including a first antenna switching network and a first digital antenna group translator, said first digital antenna group translator including a first set of analog and digital building blocks for each communication, navigation and surveillance (CNS) waveform, said first set of analog and digital building blocks including at least one of a first receive signal processing chain or a first transmit signal processing chain with digital interfaces to a first multi-channel transceiver, said first antenna switching network providing connectivity between a first plurality of antennas and said first digital antenna group translator; a second analog interface subsystem including a second antenna switching network and a second digital antenna group translator, said second digital antenna group translator including a second set of analog and digital building blocks for said each CNS waveform, said second set of analog and digital building blocks including at least one of a second receive signal processing chain or a second transmit signal processing chain with digital interfaces to a second multi-channel transceiver, said second antenna switching network providing connectivity between a second plurality of antennas and said second digital antenna group translator; a first baseband digital processing subsystem including a first network switch and said first multi-channel transceiver, said first multi-channel transceiver including a first digital modem and a first set of protocol processing components for implementing behavior of said each CNS waveform, said first network switch being communicatively coupled to said first digital antenna group translator and to said first multi-channel transceiver and providing a multiplexed data path for interconnection between said first digital antenna group translator and individual channels in said first baseband digital processing subsystem; and a second baseband digital processing subsystem including a second network switch and said second multi-channel transceiver, said second multi-channel transceiver including a second digital modem and a second set of protocol processing components for implementing behavior of said each CNS waveform, said second network switch being communicatively coupled to said second digital antenna group translator and to said second multi-channel transceiver and providing interconnection between said second digital antenna group translator and individual channels in said second baseband digital processing subsystem, wherein said first digital antenna group translator is communicatively coupled to said second network switch and said second digital antenna group translator is communicatively coupled to said first network switch so that CNS functions continue to be available after a single fault in a system component of said high availability digital radio architecture.
