ABSTRACT:
The present invention provides a time efficient and practical method for signal burst detection. The signal is first applied to a set of linear transformations and input to a one-bit analog to digital converter and stored. The stored signal is then correlated with stored replications of sinusoidal wave forms over the range of frequencies using either a random access memory (RAM) or EPROM chip. The maximum of the correlation outputs is then compared with a selected threshold to provide a decision for the existence or nonexistence of the signal. This information is used to signal the processor to proceed with the acquisition and processing of the signal to determine the frequency and phase.
