Efficient exhaustive search for binary complementary code sets

Binary complementary code sets offer a possibility that single binary codes cannot-zero aperiodic autocorrelation sidelobe levels. These code sets can be viewed as the columns of so-called complementary code matrices, or CCMs. This matrix formulation is particularly useful in gaining the insight needed for developing an efficient exhaustive search for complementary code sets. An exhaustive search approach is described, designed to find all sets of K complementary binary codes of length N, for specified N and K. Results for several cases are examined.
