Abstract
Apparatus and methods spread input symbols for transmission in multiple dimensions. When input symbols are spread over time, frequency, and code space, the resulting symbols exhibit good immunity to interference. In one embodiment, a system with a multi-tone outer code/modulation and a direct sequence spread spectrum (DSSS) inner code/modulation provides good communications performance characteristics and can be efficiently implemented.
