Abstract :
Presents a method for obtaining multilevel sequences with low crosscorrelation sidelobes. The method is based on the sidelobe suppression technique by minimax filtering. An analysis of code efficiency as well as signal/noise ratio loss is presented. Some encouraging results are obtained, compared to the method based on the LS sidelobe suppression technique, especially if the maximum sidelobe level is considered.
