Uniform complex codes with low autocorrelation sidelobes (Corresp.)
U. Somaini, Martin H. Ackroyd · IEEE Transactions on Information Theory · 1974
The problem of designing uniform-amplitude codes with good autocorrelation functions can be regarded as a problem of mlnimizing a function of several continuous variables. The application of numerical methods of minimization is shown to yield codes with lower sidelobe levels than other known codes of equal lengths. Codes with no sidelobe exceeding unity have been found for lengths as large as 18.
