The correlation values and the distribution of these correlation values for the small set of nonbinary Kasami sequences over GF(p) (p prime) are presented. The correlation results are an extension of the binary results and have p+2 correlation levels. This nonbinary Kasami set is asymptotically optimum with respect to its correlation properties. These sequences are obtained, as in the binary case, from a large primitive polynomial of degree n=2 m and a small primitive polynomial of degree m that yields a sequence length of p/sup n/-1 and maximum nontrivial correlation value of 1+p/sup m/. Nonbinary Kasami sequences are directly implemented using shift registers and are applicable for code division multiple access systems.
