Filters that reduce the sidelobes of the quadriphase-coded waveform are realized by applying the biphase-to-quadriphase transformation to the filter designs that reduce the sidelobes of the prototype biphase code. The mismatch loss is invariant under this transformation, but the resulting peak-to-sidelobe ratio (PSR) can decrease 1.5 dB maximum. An example illustrates the procedure for a compressor composed of a sidelobe reducing filter cascaded with the matched filter and a compressor realized as one mismatched filter.
