In this paper, we present results of a feasibility study of a model-independent way to measure the angle φ3 of the unitarity triangle. The method involves B±→DK± decays where the neutral D decays to the K0 Sπ+π- final state, together with the sample of decays of CP-tagged D mesons (produced, e.g. in ψ(3770)→DD̄ process) to the same final state. We consider different approaches to the extraction of φ3 and obtain the expected statistical accuracy of the φ3 measurement as a function of B and DCP statistics.
