    Abstract: Systems and methodologies are described that facilitate transmitting beac on symbols of a beacon message such that a sequence of symbols can satisfy a linear constraint over a field where the field elements can be identified w ith carriers. In this regard, a coding scheme can be applied to a beacon mes sage; the coding scheme can produce a plurality of beacon symbols to transmi t on given subcarriers. A receiving device of the beacon symbols can decode a beacon message by receiving less than the total number of symbols in a bea con message and determining the remaining symbol subcarriers based on the li near constraint. Thus, more efficient decoding of beacons is facilitated as well as resolving beacon ambiguity by figuring out which symbols satisfy lin ear constraints for the symbols, and resolving time and frequency shift by d etecting an offset that would result in satisfaction of the linear constrain t.
