Generalized Cross-correlation Properties of Chu Sequences
  In this paper, we analyze the cross-correlation properties for Chu sequences, which provide information on the distribution of the maximum magnitudes of the cross-correlation function. Furthermore, we can obtain the number of available sequences for a given maximum magnitude of the cross-correlation function and the sequence length.
