Abstract
A method for a direct sequence spread spectrum communication system comprises encoding a first signal of data in a communication channel, embedding a second signal of data as notches in the communication channel, transmitting the first signal of data and the second signal of data concurrently and at a substantially same rate across the communication channel, receiving the communication channel, decoding the first signal of data in the communication channel to interpret the first signal of data, and bit decoding the second signal of data in the communication channel to interpret the second signal of data.
