Abstract :
In this contribution, novel symbol-by-symbol (SbS)-type maximum a posteriori probability (MAP) receivers are presented for non spread-spectrum (SS) multiple-access (MAC) narrowband systems impaired by ISI and co-channel interference (CCI). The proposed decentralized type receivers minimize the error probability in the detection of the desired user message on a per-symbol basis. A practical application environment for the presented receivers can be constituted by Ethernet-type local area networks (LANs) where central offices are linked to subscribers via multitapped buses
