A discrete pseudo Wigner distribution spread spectrum detection procedure employing complex spreading sequences

Proceedings of COMSIG '94 - 1994 South African Symposium on Communications and Signal Processing, 2002
An efficient quadratic time-frequency (TF) discrete pseudo Wigner distribution (DPWD) based detection procedure is proposed for utilisation in direct sequence spread spectrum (DSSS) receivers. A class of complex generalised chirp-like (GCL) perfect-squares minimum-phase constant-amplitude-zero-autocorrelation (PS-MP CAZAC) signature or spreading ...

The Modified Discrete Wigner Distribution and its Application to Acoustic Well Logging

1984
The full wave acoustic well log gives a large amount of information about the surrounding formation, which is encoded into a complex wavetrain and is not easily interpretable. This paper presents a technique using the Wigner Distribution to recover some of the information encoded in these wavetrains.

Efficient computation of the discrete Wigner-Ville distribution

2012
To ensure that the discrete Wigner-Ville distribution (DWVD) does not contain aliasing terms, the analytic signal is normally used instead of the real signal. However, the computation of the analytic signal amounts to most of the computation time.
