Abstract :
An overlapping method (OM) for signal synthesis from modified pseudo-Wigner distributions (PWD) has been suggested. The authors present a suboptimal PWD signal synthesis algorithm which, like the OM, has a recursive structure and thus allows signal synthesis without an inherent restriction of signal length. This algorithm is called the simplified partial sum method (SPSM). While the SPSM appears to be similar to the OM in its formulation, its results are generally quite different. OM and SPSM are compared in a simple synthesis experiment and it is shown that while OM results are clearly improper, SPSM yields a satisfactory performance
