Abstract :
This paper is concerned with the identification of pass-band and baseband Hammerstein channels from cumulants of the noisy observations of the channel output. The channel is excited by communication signals such as QAM, PSK and OFDM. Exact expressions and respective algorithms involving the output cumulants are derived.
