Disclosed are systems, methods, and non-transitory computer-readable media for improved data transmissions using puncturing and binary sequences. A receiving device receives a sequenced data input that includes a set of individual values and performs a puncturing of the sequenced data input, yielding a punctured sequenced data input. The receiving device calculates correlation values for the punctured sequence data input and a set of predetermined data outputs. The receiving device determines whether any of the resulting correlation values exceeds a threshold correlation value. In response to determining that the correlation value calculated based on one of the predetermined data outputs exceeds the threshold correlation value, the receiving device determines that the sequenced data input corresponds to the predetermined data output.
