Efficient Mutually Orthogonal Golay Complementary Set-Based Zero-Correlation Zone Sequence Set Correlator

An efficient implementation of zero-correlation-zone (ZCZ) sequence set correlators is of particular interest for integrated circuit realizations of phase-coded continuous-wave multiple-input multiple-output radar systems. Such systems require a correlation with all transmitted sequence set members at every receiver. We present an approach for an efficient circuit realization of such a sequence set correlator for a subset of mutually orthogonal Golay complementary set-based ZCZ sequence sets. Furthermore, we analyze and optimize the resource requirement. A logarithmic instead of a linear growth of the required adders could be achieved by the proposed implementation.
