1. A method for modulating a signal in a communication system, the method comprising:

  • spreading a data frame with a pseudorandom noise code at a transmitter to a spreading factor;

    generating a data stream comprising a first component, wherein the data frame is assigned to the first component;

    transmitting the data stream at a time wherein the time is determined in part from a start slot time plus a random chip delay while a second transmitter transmits at a second time a second data stream comprising a second data frame spread with the pseudorandom noise code to a second spreading factor wherein the second time is determined in part from the start slot time such that both the data stream and the second data stream are received.
