Abstract
A device includes circuitry configured to spread one or more symbols with one or more orthogonal codes into spread signals having a predetermined number of bits. The amplitude of the spread signals is modified via one or more layer coefficients and the spread signals are multiplexed into a layered transmit signal.

20. A device comprising:
circuitry configured to recover a highest received signal layer by reverse spreading a received signal with the one or more orthogonal codes, re-spread the highest received signal layer with one or more orthogonal codes and multiply a corresponding spread signal by an associated layer coefficient, and subtract a re-spread signal from the received signal to recover one or more lower received signal layers.
