Minimum-error-probability single-user detection for ISI-impaired narrow-band multiuser systems

The goal of this contribution is to give some insight into the cochannel in terference (CCI) suppression capability of novel symbol-by-symbol-type maxi mum a posteriori probability single-user receivers for nonspread-spectrum m ultiuser narrow-band systems impaired by intersymbol interference and CCI. The presented multiuser receivers minimize the error probability in the det ection of the desired user message on a per-symbol basis. Practical applica tion environments for the developed detectors can be constituted by Etherne t-type LANs and DSL-based high-throughput links connecting central offices to subscribers.
