Some autocorrelation properties of phase-coded waveforms

In this paper we study some autocorrelation properties of a train of identical signals overlaid with a phase coding. Prior publications have investigated this problem under the assumption that, for the purpose of the phase coding, the original (uncoded) signal forming the train is divided into a number of bits that are either all identical or all distinct. This paper extends the discussion to the case of repeated bits. We derive and analyze sufficient conditions for cancelation of the waveform´s autocorrelation sidelobes located around the main lobe area.
