Method for Time Coding of Asynchronous Data Transmission

Authors: David J Moretti; NAVAL UNDERSEA WARFARE CENTER DIV NEWPORT RI
Abstract:
A method of transmitting data includes synchronizing a system clock with a real time clock. Digital data is collected from multiple sources at a system clock time. A sample counter provides a count for each system clock time. The digital data for each source is associated with the count. A data cell is composed from the digital data associated with at least one count and a source identifier. A data frame is created from the data cells from every source. A cell frame is created from a plurality of data frames, and a time frame is composed from a plurality of cell frames. A heads-up cell including the count is transmitted before the time frame. A time/count cell including the count and the real time is transmitted with the associated time frame.
