Multiple access communication over the power line channel: a CDMA approach

Abstract

This paper deals with CDMA based multiple access communication over an in-house power line channel. Three receivers are described: a RAKE receiver; a MMSE equalizer which estimates the symbols sent at the chip rate, assuming these symbols are i.d.d. (independent and identically distributed); a MMSE equalizer which acts directly on the information symbols. Performance of these receivers is assessed with a special emphasis on the tradeoff between performance and complexity.
