Abstract
A spread spectrum communications method is based on time compression in which a sampled message signal at a first rate is transmitted at a higher sampling rate. Robustness is achieved by dividing the signal into overlapping segments, transmitting each segment fast enough so that the segments no longer overlap. The segments are received and the data signal reconstructed by overlap-adding the segments.
