Patent ID: 8675711

Claim:
A method of transmitting a signal to one or more receivers using spread spectrum signals, the method comprising: at a transmitter having a processor and memory: obtaining information identifying a plurality of discontinuous discrete bandwidth intervals that are only available for transmission at an energy level below a noise floor; generating a signal; separating the signal into a plurality of bits, wherein each of the plurality of bits is configured for transmission in a predefined bandwidth that corresponds to a minimum amount of spectrum required to transmit the bit in a predefined duration; and transmitting, the plurality of bits in the plurality of discontinuous discrete bandwidth intervals with an energy level such that each of the plurality of bits are transmitted below the noise floor to a satellite via an uplink for further transmission to the one or more receivers via a downlink, wherein at least two bits of the plurality of bits are transmitted in each of the plurality of discontinuous discrete bandwidth intervals and the at least two bits have different center frequencies and are transmitted at the same time, wherein a respective discontinuous discrete bandwidth interval of the plurality of discontinuous discrete bandwidth intervals includes at least twice the minimum amount of bandwidth necessary to transmit a respective bit of the plurality of bits.
