Abstract
The spread spectrum communication system terminal comprises a first subsystem including a first arrangement to encode a locally generally digital data with an error correcting code, a second arrangement for spectrum spreading of the encoded locally generated digital data in at least one mode of operation of the communication system terminal, a third arrangement to receive remotely generated error correcting code encoded digitla data spectrum spread in the one mode of operation and a fourth arrangement to recover the remotely generated digital data. In addition, a second subsystem includes a fifth arrangement frequency hopping the encoded locally generated digital data prior to transmission to a remote location and a sixth arrangement frequency dehopping the encoded remotely generated digital data received from the remote location. A third subsystem is also provided including a seventh arrangement to provide a predetermined signal for spectrum spreading the encoded locally generated digital data in the one mode of operation and to couple the encoded locally generated digital data to the fifth arrangement and an eighth arrangement to provide a reference frequency for the frequency ho…
