Abstract

A method includes receiving a first signal and updating a bitmap index responsive to the first signal. The bitmap index includes a plurality of bit strings, where a value stored in a particular location in each of the bit strings indicates whether a corresponding signal associated with a signal source has been received. Updating the bitmap index responsive to the first signal includes updating a first bit of the bitmap index and updating a first metadata value stored in the bitmap index. The method also includes receiving a second signal and updating the bitmap index responsive to the second signal. Updating the bitmap index responsive to the second signal includes updating a second bit of the bitmap index and updating a second metadata value stored in the bitmap index.
