SPREAD SPECTRUM METHOD AND APPARATUS

摘要

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.

1. A method, comprising:
dividing a first message signal associated with a message rate fm into a series of overlapping segments having a predetermined length and overlap; and transmitting the segments serially at a channel rate fC that is higher than the message rate fm, wherein the channel rate fC is selected based on the predetermined length and overlap so as to accommodate redundancy associated with the division into overlapping segments.
