WLC13-1: An Array for Constructing Perfect Sequences and Its Applications in OFDM-CDMA Systems
Chih–Peng Li, Wei‐Chieh Huang · Globecom · 2006
A complex array for constructing perfect sequences is presented in this paper. The row sequences and their discrete Fourier transform form two sets of perfect sequences. The column sequences are orthogonal to each other for any cyclic shift. In addition, any combination of the column sequences with complex weighting coefficients of equal amplitude is also a perfect sequence. Applications of the constructed sequences are presented for OFDM-CDMA systems.
