TC-93-06 A research submitted in partial fulfillment of the requirement for the degree of Master of Engineering, School of Engineering and Technology Research Studies Project Report (M.Eng.) - Asian Institute of Technology, 1993 Sorting algorithms have been proposed for finding subsets of Direct Sequence Spread Spectrum Multiple Access (DS/SSMA) signature sequences with small cross-correlation magnitudes. Two algorithms, the Discarding (DS)-Algorithm and the Enhancing (ES)-Algorithm, have been used to investigate the performance of the subset mean AIP value under worst case interference conditions. Based on an AIP testing criterion, the ES-Algorithm used in conjunction with the Maximum Sidelobe Energy (MSE) initial phase condition has successfully achieved smaller subset mean AIP values when the subset size is small. The Signal-to-Noise Ratio (SNR) is used as a measure at the correlator output. The SNR performance of mean AIP subsets using both algorithms is evaluated and compared with expected values for random binary sequences.
