Performance of a correlation demodulator in the presence of a speech signal

Research output: Contribution to journalArticlepeer-review

2 Scopus citations


The performance of a correlation demodulator (CD) in a channel with an additive speech signal and background noise is analyzed. Expression of eenergy loss due to the influence of the speech signal and of probability of error are obtained. For that purpose the speech signal is considered as a random combination of vowel, consonant and a pause. Moreover, the vowels as well as the consonants are modelled as response of some linear time invariant (LTI) systems to white noise. As an illustration the case of an antipodal (BPSK) signal is considered. The theoretical results are in very good agreement with experiment.
