Abstract :
The Prometheus orthonormal set (PONS) represents a Hadamard-type sequence construction with advantageous autocorrelation, spectrum and peak-to-average power ratio properties. The PONS-based orthogonal variable spreading factor (OVSF) sequences are proposed for channelization in wideband code-division multiple access. A duocode version is shown to yield the same code capacity as Walsh-based OVSF. The duocode OVSF-PONS channelization offers a strong alternative to Walsh-based constructions in next generation wireless communications, due its superior sequence properties which can be implemented at the expense of slightly increased complexity.
