Abstract:
A spread-spectrum system comprising:assignment means for assigning each information signal, of a plurality of information signals arriving at an input to said spread-spectrum system, with several information signals of the plurality of information signals having several different channel rates, to a message-code signal, of a plurality of message-code signals, with each of the plurality of message-code signals supporting a pre-determined information-channel rate, with each message-code signal in the plurality of message-code signals different from other message-code signals in the plurality of message-code signals; spread-spectrum processing means for generating a pilot-code signal, and for spread-spectrum processing the plurality of information signals with the plurality of message-code signals to generate a plurality of spread-spectrum processed-message signals, respectively, with the plurality of message-code signals synchronized to the pilot-code signal; call-processing means for providing a call-type signal corresponding to the information signal rate for the several information signals having several different channel rates; and information-channel-mode modification means, coupled to said assignment means and to said spread-spectrum processing means, and responsive to the call-type signal, for changing a combination of the plurality of information signals and the plurality of message-code signals to support the several different channel rates for the several information signals having several different channel rates.
