| Summary: | 碩士 === 輔仁大學 === 電子工程學系 === 98 === This paper presents the analysis of the accurate performance for the joint equalizer and diversity receiver with fractionally spaced decision-feedback equalizer (FSDFE) based on the minimum mean-square-error (MMSE) to eliminate cyclostationary cochannel interference (CCI) over a fading channel. The receiver uses a feedforward filter (FFF) having fractional tap spacing on each diversity path to eliminate precursive and CCI, when leaving the combined, postcursive intersymbol interference (ISI) to be mitigated by the symbol-spaced feedback filter (FBF). In calculating the average error probability for each fading channel is calaulated fast and accurately using Gaussian quadrature rules (GQR) which can approximate the probability density function of the combined output with ISI and CCI.
