A method for multipath resistant waveform coding is provided. The method adds a chip extension to an optimally designed waveform set to compensate for an expected time shift in the radio channel during the transmission and demodulation of the transmitted waveform. The chip extension can be added to the beginning and/or end of the input waveform. The number of chip extensions added is based on the expected multipath time delay in the radio channel. The chip extension method can be used in BPSK, QPSK, QBPSK, and a modified Quadrature-BPSK encoding scheme.
