Abstract
A transmitter spreads a data signal with an inner spreading code to produce a first spread signal; modulates a link mask onto the first spread signal to produce a masked signal; spreads the masked signal with an outer spreading code to produce a second spread signal; and modulates the second spread signal onto a multitone transmission signal. The link mask can include at least one of a destination mask and a source mask. A network mask might be modulated onto the second spread signal to conceal cyclic features in a spreading format used to spread the data signal and/or the first masked signal. A receiver demodulates a received multitone transmission to produce at least one demodulated signal; demasks the at least one demodulated signal to produce at least one demasked signal; and despreads the at least one demasked signal using an adaptation algorithm to remove the outer spreading code.
