Abstract
A spread-spectrum system having an assignor, a spread-spectrum processor, a call processor, and an information-channel-mode modifier. The assignor assigns each information signal arriving at the spread-spectrum system to a message-code signal. Each of the message-code signals supports a pre-determined information-channel rate. Several information signals have different channel rates, and each information signal is assigned according to the required channel rate. The spread-spectrum processor generates a pilot-code signal, and spread-spectrum processes the information signals with the message-code signals to generate a plurality of spread-spectrum processed-message signals, respectively. The message-code signals are synchronized to the pilot-code signal. The call processor provides a call-type signal corresponding to the information signal rate for the several information signals having several different channel rates. In response to the call-type signal, the information-channel-mode modifier changes a combination of the information signals and the message-code signals to support the several different channel rates for the several information signals having several different channel rates.
