Abstract :
An adaptive near far resistant (NEFAR) receiver architecture based on fractionally spaced decision feedback equalisation (FS-DFE) is addressed. The FS-DFE detector is found to offer significant advantages compared to the decorrelating detector of Lupas and Verdu (1990). The detection process does not make explicit use of the interfering sequences and can act as a multipath diversity combiner. It is shown that even for non-near-far scenarios the FS-DFE detector offers significant gains in spectral-efficiency as compared to the conventional detector
