A method and apparatus transmit (400, 500) and receive (600) information as a power hopped direct sequence spread spectrum signal. The information is encoded (402) with a predetermined spreading sequence to produce a direct sequence spread spectrum, or DSSS signal, and a plurality of simultaneous radio signals operating on a plurality of frequency slots (F1-F10) and modulated by the DSSS signal are generated (404, 406, 504). The output power of individual ones of the plurality of simultaneous radio signals is adjusted (408, 502) periodically according to a predetermined power hopping sequence. The information is received by demodulating (602) and processing (604-620) the signal from at least one of the plurality of frequency slots.
