This paper discusses a set of sequences with a zero correlation zone such that their Fourier transform over GF(p) corresponding to the Hadamard transform over GF(p) takes only unit magnitude, called a bent ZCZ code. The constructions and properties of polyphase bent ZCZ codes of period pn including bi-phase and quadriphase ones are clarified.
