Abstract :
Two solutions to the problem of recovering deterministic signals (objects) from the bispectrum of noisy observations of the signal are proposed. Some of the tradeoffs involved in using bispectrum-based reconstruction approaches vis-a-vis other techniques are discussed. Applications to several types of problems are discussed. Four simulation examples are given
