Abstract

A method of communicating digital information as a stream of binary chip values impressed on a transmitted signal during a series of discrete transmitter chip intervals. During a preamble period, the transmitter provides a predetermined transmitter clock signal having a series of different values during a series of crumb intervals, each such crumb interval being a rational fraction of one transmitter chip interval. The receiver generates plural series of receiver chip intervals offset in time from one another. During the preamble period, the receiver subdivides each chip interval of each such series into receiver crumb intervals. The receiver selects one series of receiver chip intervals for which the values of the detected signal best match a template corresponding to the transmitter clock signal. This selected series of receiver chip intervals is the series best synchronized with the transmitter chip intervals. After the preamble period, the receiver recovers the binary chip values by assigning values to successive intervals in the selected series of receiver chip intervals according to the value of the detected signal for each interval in that selected series.
