Abstract

Notice of Violation of IEEE Publication Principles<br><br>After careful and considered review of the content and authorship of this paper by a duly constituted committee, this paper has been found to be in violation of IEEE's Publication Principles.<br><br>This paper is a duplication of the original text from the paper cited below. The original text was copied without attribution (including appropriate references to the original author(s) and/or paper title) and without permission.<br><br>Due to the nature of this violation, reasonable effort should be made to remove all past references to this paper, and future references should be made to the following article:<br><br>R. Kwan and C. Leung, "Optimal Detection of a BPSK Signal Contaminated by Interference and Noise," IEEE Comm. Lett., vol. 6, pp. 225-227, June 2002.<br><br> <br/> The problem of detecting a desired binary phase-shift keying (BPSK) modulated bit in the presence of a second BPSK modulated interfering signal and additive white Gaussian noise is considered. Given knowledge of the amplitudes and phases of the unmodulated signals received from the two transmitters, the minimum achievable bit error rate is obtained and compared with that for a conventional matched filter detector. It is shown that the performance difference can be quite large when the interfering signal is strong.
