Abstract.This study investigates the potential of an Electron-Positron Linear Collider for measuring resonance parameters of Higgs bosons beyond the mass range studied so far. The analysis is based on the reconstruction of events from the Higgs-strahlung process $\mathrm{e}^ + \mathrm{e}^-\to\mathrm{HZ}$. It is shown that the total width $\Gamma_{tot}^{\mathrm{H}}$, the mass mH and the event rate N can be measured from the mass spectrum in a model independent way. Also, the branching ratios BR HWW and BR HZZ can be measured, assuming these are the only relevant Higgs decay modes. The simulation includes realistic detector effects and all relevant Standard Model background processes. Results are given for mH = 200-320 GeV assuming ${\cal \int\!\! L} = 500$ fb-1 integrated luminosity at a collision energy $\sqrt{s} = 500$ GeV.
